In one conventional technique, a memory cell is read by applying a small bias to the drain of the transistor, as well as a gate bias that is above the threshold voltage of the transistor. In this regard, in the context of a memory cell using an N-type transistor, a positive voltage may be applied to one or more of the word lines 28 to enable the reading of memory cells associated with such word lines. The magnitude of the drain current is determined or influenced by the charge stored in the electrically floating body region of the transistor. Likewise, a conventional readout technique can determine the state of a memory cell by sensing a magnitude of a channel current supplied / generated according to application of a voltage to a gate of a transistor of a memory cell. A floating body memory cell may have two or more different current states corresponding to two or more different logic states (e.g., two different current states corresponding to two different logic states " 1 " and " 0 & Condition / status).

In short, conventional write programming techniques for memory cells with N-channel type transistors often require channel impact ionization (see FIG. 3A), or band-to-band tunneling (Gate-Induced Drain Leakage (GIDL)) (Fig. 3B), which provides an excess of majority carriers. (FIG. 4A), or drain side and source side hole removal (FIG. 4B) using, for example, back gate pulsing (FIG. 4C) .

Conventional programming / reading techniques often result in relatively large power consumption (due to, for example, a high " 0 " write current) and relatively small memory programming windows. The present invention, in one aspect, relates to a combination of programming / reading methods that enable relatively lower power memory programming and provide a relatively larger memory programming window (e.g. both, In comparison to the programming technique of. This new approach also provides a more desirable power consumption and a floating body memory cell that can include improved retention characteristics.

When an inversion channel is formed, a continuous electrical channel is provided from the source region to the body region. The reversal channel of a conventional device spans the entire body region, with the source and drain regions being configured to lie under the gate. In this manner, by applying a suitable gate voltage to a conventional device, the inversion channel can form a continuous electrical channel from the source to the drain region.

However, unlike conventional MOSFET devices, the source 20 and / or drain 22 regions of one embodiment are not located under the gate 16 in any portion of the source 20 and / or drain 22 regions . The configuration of the source 20 and / or drain 22 regions of one embodiment may be implemented by controlling the configuration and / or size of the doped source 20 and / or doped drain 22 regions of the transistor . Since only the first portion 18-1 of the body region is located under the gate 16, when an appropriate control signal is applied to the gate 16, the charge that can be accumulated, or the inversion channel that may be formed, Can be found only in the first part 18-1. No charge accumulates in the second portion 18-2 and / or the third portion 18-3 and no inversion channel is formed because these portions are not located below the gate 16 to be.

As a result of applying the gate voltage to the transistor 14, charge is built up in the first portion 18-1 of the body region 18, but the accumulated charge and / or the absence of a continuous inversion channel between the source and drain regions The current does not flow in the body region 18. The discrete configuration of the first portion 18-1 of the body region for the source and drain regions thus serves as an " open circuit " for the flow of current between the source region 20 and the drain region 22 . Thus, by virtue of any charge present in body region 18, transistor 14 can operate as a capacitor. The region of the charge of the body 18-1 is disconnected from the source region 20 and / or the drain region 22.

Figure 7A shows an electrically floating body transistor 14 comprising a MOS capacitor " component " and an intrinsic bipolar transistor " component " under one embodiment. In one aspect, the present invention utilizes an intrinsic bipolar transistor " component " to program / write the memory cell 12 as well as read it. In this regard, the intrinsic bipolar transistor generates and / or generates a source or bipolar transistor current that is used to program / write the data state to the memory cell 12 and read the data state of the memory cell 12.

The bipolar transistor 14 of one embodiment has a floating body, which means that the potential is not fixed and is in the " floating " state. For example, the potential depends on the charge at the gate. Conventional bipolar transistors require respective base currents, emitter currents, and collector currents for proper operation. However, since there is no base contact such as that found in conventional bipolyFETs, any base of transistor 14 in this embodiment is not floated, fixed, and thus the current of this transistor is subjected to impact ionization in the body region Quot; source " current generated by the " source "

The characteristic curve shows a significant increase in the source current above a certain threshold of the potential difference (" source-drain potential difference ") between the applied source voltage and the applied drain voltage. The reason for this is that the voltage difference above a certain threshold generates a high electric field in the body region. The high electric field causes impact ionization in the first portion 18-1 of the body region 18, which is the process by which electrons, or particles with sufficient energy, generate many carriers, i.e., holes. The impact ionization drives the majority carriers into the body region, thereby increasing the body potential while the majority carrier of N flows into the drain (or source) region. The increased body potential causes an increase in the source current in the body region. Thus, an excessive majority carrier in the body region generates the source current of transistor 14 in one embodiment.

The logic " 1 " programming operation of this embodiment includes applying a two stage control signal, during which the gate voltage is changed from the first voltage level to the second voltage level. During operation, when writing or programming a logic " 1 ", in one embodiment, control signals (e.g., Vg = 0.5V, Vs = 0V and Vd = 2.5V) The source region 20 and the drain region 22 of the transistor 14 of the memory cell 12, respectively (Fig. 8A). The stage 1 control signal can cause the accumulation of minority carriers (not shown in the figure) in the electrically floating body 18. Any minority carriers that would be present in the body region 18 may be used as a result of the polarity (e.g., positive) of the control signal applied to the gate using the stage 1 control signal, 1). A minority carrier may (but is not limited to) accumulate in the first portion 18-1 region under the gate.

The inversion channel has the same type as the source and drain regions (e.g., the N-type in the nMOS FET) and functions to electrically connect the source and drain regions.

The reason that no inversion channel is formed in the transistor 14 is that the first portion 18-1 of the body 18 is electrically " disconnected " from the source 20 and drain 22 regions, The time required to form the inversion channel for a while is considerably longer than, for example, the writing time. Thus, taking into account that the recording time of one embodiment is approximately 1 to 10 nanoseconds, it is contemplated that the time required to generate the inversion channel in the first part 18-1 of the body to be disconnected is much longer than 10 nanoseconds An inversion channel is not generated in the transistor 14 during normal program operation. Likewise, the minority carriers are hardly accumulated or completely accumulated in the body region.

In addition, even if an inversion channel is formed in the first portion 18-1 of the body region as a result of the gate voltage, the inversion channel is formed between the second portion 18-2 and the third portion 18-3 ). Because these regions 18-2 / 18-3 are not located under the gate. Any inverting channel under the embodiment of the present invention will therefore be " disconnected " from the source 20 and drain 22 regions, i.e., discontinuous with the source 20 and drain 22 regions.

The absence of an inverting channel of a transistor in one embodiment, or the presence of a discontinuous inverted channel (if formed), is reversed, as opposed to a conventional transistor in which an inverting channel is formed, diffused from source to drain, to be. However, the configuration of this conventional device is such that the gate lies on the entire body region between the source region and the drain region and the programming time is a length ensuring the formation of an inversion channel when an appropriate voltage is applied, To form a continuous inversion channel that " connects " the source and drain regions.

The stage 1 control signal also generates or provides the source current to the electrically floating body region 18 of the transistor 14. More specifically, the potential difference (e.g., 2.5 volts) between the source voltage and the drain voltage is greater than the threshold required to turn on the bipolar transistor. The source current of the transistor thus causes or generates an impact ionization and / or avalanche multiplication phenomenon between the particles in the electrically floating body region 18. As noted above, the impact ionization creates, provides, or generates an excessive number of carriers 806 in the electrically floating body region 18 of the transistor 14 of the memory cell 12.

In particular, the source current responsible for impact ionization and / or electron multiplication in the electrically floating body region 18 is coupled to the gate 16 of the transistor 14, together with the potential difference between the source 20 and drain 22 regions. Or is induced by a control signal applied to the control terminal. This control signal may raise or increase the potential of the body region 18 to induce channel impact ionization that " turns on, " generates, causes, or induces the source current of the transistor 14. [ One advantage of the proposed write / program technique is that an oversized majority carrier 806 can be generated and stored in the electrically floating body region 18 of the transistor 14.

As noted above, when writing or programming a logic " 1 ", a stage 2 control signal is applied to the transistor. The stage 2 control signal is applied to stage 1 and to a predetermined voltage (each) applied to gate 16, source region 20 and drain region 22 of transistor 14 of memory cell 12 , Vg = -1.0 V, Vs = 0 V, and Vd = 2.5 V). As a result of the polarity (e.g., negative) of the control signal applied to the gate using the stage 2 control signal, a majority carrier 806 of the body region 18 is coupled to the first portion 18-1 of the body region, (Fig. 8B). The polarity (e.g., negative) of the gate signal combined with the floating body allows the majority carriers 806 to be trapped or " stored " near the surface of the first portion 18-1 of the body region . In this manner, the body region 18 of the transistor " stores " charges (e.g., functions like a capacitor). Thus, in this embodiment, the specified voltage of the Stage 1 and Stage 2 control signals is programmed to the memory cell 12 through impact ionization and / or electronic propagation in the electrically floating body region 18 , Or records.

The logic " 0 " programming operation of one embodiment includes applying a two stage control signal, during which the gate voltage is changed from a first voltage level to a second voltage level. In one embodiment, during operation, when a logic " 0 " is written or programmed, it is first of all to have a voltage (e.g., Vg = 0.5V, Vs = 0.5V and Vd = 2.5V) A control signal is applied to the gate 16, the source region 20 and the drain region 22 of the transistor 14 of the memory cell 12, respectively (Fig. 9A). By the stage 1 control signal, the minority carriers can be accumulated in the electrically floating body 18. More specifically, the gate 16 of the first portion 18-1 of the body region, as described above, is used as a result of the polarity (e.g., amount) of the control signal applied to the gate using the stage 1 control signal. Below, in the region close to the boundary of the gate dielectric 32 and the electrically floating body 18, accumulation of minority carriers occurs. Is present in the first portion 18-1 of the body region as a result of the accumulation of any fractional carrier gate voltages and thus does not accumulate in the second portion 18-2 and third portion 18-3 of the body region Do not. Thus, the accumulated charge in the body region 18 is discontinuous with the source region 20 and the drain region 22.

However, the potential difference between the source voltage and the drain voltage of the stage 1 control signal is smaller than the threshold value required to turn on the transistor 14. [ As a result, no impact ionization occurs between the particles in the body region 18, and no bipolar, or source current, is generated in the electrically floating body region 18. So that no excessive majority carriers are produced in the electrically floating body region 18 of the transistor 14 of the memory cell 12. [

As noted above, when writing or programming a logic " 0 ", the stage 2 control signal is applied to the transistor 14. The stage 2 control signal is applied to the gate 16, source region 20 and drain region 22 of the transistor 14 of the memory cell 12 following Stage 1, For example, Vg = -1.0v, Vs = 0.5v, and Vd = 2.5v. The polarity (e.g., negative) of the gate signal causes any accumulated minority carriers to be moved from the electrically floating body of the transistor 14 through one or more of the source region 20 and the drain region 22. In addition, the polarity (e.g., negative) of the gate signal may cause any minority carriers remaining in the body region 18 to be trapped or " stored " near the surface of the first portion of the body region 18 . This is because a large number of carriers are absent in the body region 18 and in this way the specified voltage of the stage 1 and stage 2 control signals can program or write logic " 0 "

Generally, by forming a semiconductor on the insulator 1302, a transistor 14 is formed. An insulating layer and a gate are formed over the first portion of the semiconductor (1304). A spacer is formed 1306 over the second and third portions of the semiconductor, and the spacer is adjacent to the insulating layer. The first, second and third portions of the semiconductor together form a floating body region. After forming the spacers, implanting the impurity into the fourth portion of the semiconductor (1308) by forming the source region (1308) continues formation of the transistor (14). The fourth portion of the semiconductor is adjacent to the second portion. After forming the spacers, a drain region is also formed 1308 by implanting the impurity into the fifth portion of the semiconductor.

More specifically, when assembling the transistor 14, the gate may be formed and used as a mask during implantation of the semiconductor to form the source and drain regions of the device. The spacers are then formed before any implantation, or doping, of the semiconductor, so that all implantation of the semiconductor (e.g., implanting to form source and drain) can be performed after formation of the spacer . This results in a gate being formed, followed by a first implanting process (e.g., to form a lightly-doped portion of the source and drain regions), followed by the formation of spacers , Followed by a second implanting process (e.g., to form a highly-doped portion of the source and drain regions, for example).

Implanting is effected only after the formation of the spacer so that the body region includes the second portion 18-2 and / or the third portion 18-3, thereby extending beyond the extended side border of the gate So that a source and / or drain region is created. The second portion 18-2 and / or the third portion 18-3 of the body region serves to prevent any reversal channels from being formed across the entire body region of the device, Likewise, the region of the body region under which the channel is formed is not continuous with the source and drain regions. Thus, if a proper gate voltage is applied to the material of the body region, the charge accumulates in the body region of the polybasic, but no inversion channel is formed between the source and / or drain, and any accumulated charge is transferred from the source and / The current does not flow between the source region and the drain region.

Alternatively, however, the embodiment of the transistor 14 described herein produces a relatively lower potential difference between the source region and the drain region during a write operation. The lower potential difference results from the previously described device configuration including increased spacing between the source and drain regions due to the configuration (e.g., size, shape, etc.) of the source and drain regions for the gate region. Since the electric field potential is considerably reduced in accordance with its design, the gate oxide region can be made thinner.
