Invention Description (2) However, the voltage that the NMOS transistor can send is limited by the threshold voltage Vt of the transistor. If the gate voltage Vg is applied to the gate of the NMOS transistor, the maximum voltage that can be sent from the source to the drain is U-Vt. If the maximum voltage generated by the voltage generator is Vpp (approximately 20V), it is expected that when the transistor transmits or switches the high voltage, it can transmit Vpp without causing a threshold voltage drop. In other words, Vpp should be transmitted instead of Vpp-Vt. Therefore, in order to transmit a high voltage Vpp through an NMOS device, its gate voltage should be boosted to at least a threshold voltage Vt that is greater than the gate voltage, so that the voltage applied to the NMOS transmission transistor gate is Vpp + Vt. The traditional circuit for transmitting high voltage Vpp is shown in Figure 1. The circuit type shown in Figure 1 is very important in the application of NAND flash memory, especially decoding circuits such as decoding and high-voltage multiplexer. Unfortunately, please read the "Back-Note" item before you fill out this page. Binding the circuit in Figure 1 has several major shortcomings. The first disadvantage is that the lower the power supply voltage Vcc, the worse the circuit performance is. Moreover, when the power supply voltage Vcc is less than the threshold voltages VtM2 and VtM3 of the transistors M2 and M3, the circuit will not operate. In order to transfer Vpp to the output OUT, node B (connected to the gate of M3) must be boosted to Vpp + VtM3. In order to boost node B to Vpp + VtM3, node A must be boosted to Vpp + VtM3 + VtM2e. When the power supply is about 3V and the threshold power is about 1.5V, the circuit in Figure 1 will be due to the body effect. (Body effect) without acting normally. In order to boost node A to Vpp + VtM3 + VtM2, the following inequality must be true:

Description of the invention (3) Xiang Cheshi, consider the following example. If the pass through of the oscillator is 0V, node A will be boosted to Vpp. When the oscillator rises to Vcc, the voltage at node A will be increased to Vpp + by the network because the voltage at the two ends of the container will not change instantaneously. Vcc. The current situation does not consider the parasitic capacitances of virtual nodes A and B, but its existence is not ignored in the present invention. Transistor M2 charges Node B to Vpp + Vcc-VtM2. The output OUT transmitted by transistor M3 becomes the lower of Vpp and Vpp + Vcc-VtM2-VtM3. If the voltage at node B is higher than Vpp by VtM3, the output voltage Vout will be increased to Vpp. Unless Vcc & VtM2 + VtM3, the transistor M3 will saturate and the output OUT will be less than Vpp. Transistor HI provides the load that is pumped to node B and adjusts the voltage of node A. When the DECODE input is Vcc, transistor M4 is turned off and the boost circuit is enabled so that the output OUT is pulled to Vpp. No, when the DECODE input is grounded, transistor H4 pulls the node to ground potential, so that transistor M3 remains in the cutoff state, so the output OUT is not driven. In order for the circuit in Figure 1 to operate at a low supply voltage of 3V or less, the threshold voltages VtM2 and VtM3 of the transistors M2 and M3 must be very low. However, various methods of reducing the threshold voltage of the transistor will cause a large leakage current from the source to the drain when the 霣 crystal is turned off. Typically, the high-voltage transmission gate shown in FIG. 1 is used to drive a block line of a memory array during a programming operation. Billion body arrays can have thousands of block lines. Often when writing a block, other blocks are not. In this case, only one block line is raised to Vpp, and the others are not raised to Vpp. If the transistor M3 becomes a low threshold device, and each —-------- I clothing-:-^-ΐτ ------ ^ * (Please read the back L first Note: Please fill in this again 1) This paper size applies Chinese National Standard (CNS) A4 specification (210X 297 mm) 3 9 1474 B7 V.

Description of the invention (5) High voltage transmission that works normally without the use of an electric crystal with very low threshold . By the same token, there is a need for a high-frequency brake that does not needlessly risk thermal switching in the discharge transistor. Invention 槪 酉 Fu Tong ’s high-K NMOS transmission gate is boosted to a threshold voltage two transistors higher than the high voltage to be transmitted. This limits both the lowest supply voltage and the highest threshold voltage of the transistor; further, boosting the internal node to a threshold voltage higher than the high voltage of the two transistors will make all transistors connected to these nodes增加 Increased risk of joint collapse. Therefore, one of the goals of the present invention is to create a high-voltage Fu gate, which can transmit the entire high voltage to the output terminal with only a minimum boost to the internal nodes. According to the present invention, two NMOS boost transistors have their sources connected to a high voltage input, and their drains and gates are pseudo-cross connected. Two coupling capacitors connect two inverting clocks to the gates of two cross-connected boost transistors. The gate of an NMOS transmission transistor is connected to the source of one of the NMOS boost transistors, the drain is connected to the high-voltage input terminal, and the source is connected to the output terminal. The inverting clock connects the gate network of the IS transistor to a higher voltage than its threshold voltage, so the capacitor is charged and the voltage at the source of the boosted Y transistor is increased. As a result, the gate of the HMOS transmission transistor is raised to a threshold voltage higher than the input voltage of the high-voltage wheel, so the transmission transistor can transmit the high voltage to the output terminal. In one embodiment of the present invention, two diode-connected piezoelectric crystals connect the gate of a boost transistor to a high-voltage input terminal.

Description of the invention (8) A Charge to VPP 0 When CLK drops to zero and / CLK rises to V c C 1 Transistor M 1 cuts off »and capacitor The voltage at node A is increased by V c CC 1 / (C1 + CB). Where CA represents the total capacitance between node A and ground. Capacitance CA is the drain capacitance of transistors M1 and M6, and the capacitance of transistor M2. Sum of gate capacitance 0 When CLK is Vcc, transistor M2 charges node B to Vp P 0 typically »Vp P is generated by a limited capacity charge pump. During the programming operation, »Vp P will typically increase linearly from zero to high voltage, as shown by track 602 in Figure 6. The slope of the increase in V p p is determined by the capacity of the charge pump. 〇 It is expected that in the optional transmission gate, the change trajectory of nodes A and B and the output OUT can be as close as possible to V p p. In order for CLK and / CLK to rise, the transistors M1 and M2 can be switched from off to on. »The following inequality must be satisfied: Vc C * C 1 / (C1 + CB) > VtM 1 (inequality 1) Vc c% C2 / (C2 + CA) > VtM2 (Inequality 2) The threshold voltages of the transistors M1 and M2 are typically equal (VtMl = VtM2). Node B has one more circuit element connected to it, which is the gate of the transmission transistor M5; therefore, the first inequality is typically more difficult to satisfy. The size of capacitor C1 can be increased to ensure that this inequality is satisfied. In general, when the transistors M1 and M2 are switched off and on, after several clock cycles, the power at node B is equal to Vpp.

於CLK的上昇緣,電容性的綃接開始將節點B充電至Vpp + Vcc * Cl / (Cl + CB),但調壓電晶體 M4接箸便將節點 B放電至 Vpp + VtM4。當電荷泵增加 Vpp和節點B的電 壓時,本體效應會增加電晶體M4的臨限電壓 VtM4 。因 此,節點 B緊隨在 CLK上昇緣後之電壓 Vpp + Vcc * C1 / (Cl + CB)和恰在CLK下降緣結束前之電壓 Vpp

Invention Explanation (12) The transistor M3 discharges node A to Vpp + VtM3 before the falling of CLK is green. Similarly, although node B is boosted to Vpp + V cc * C 1 / (C 1 + CB) at the rising edge of / CLK, the piezoelectric crystal M 4 discharges node B to Vpp before the falling edge of / CLK + VtM4. Further, if the charge pump (not shown) that generates Vpp is turned off and VPP is discharged to some lower voltage (Vcc or ground), the transistor M3 used in the circuit 300 of the embodiment according to the present invention is used. And M4 make nodes A and B automatically discharge with Vpp via transistors M3 and M4, the discharge situation is as Vpp discharge, maintain a threshold voltage Vt higher than Vpp. In the embodiment 300 shown in FIG. 3, the voltages at nodes A and B are adjusted so that when Vpp decreases, the voltages at nodes A and B also decrease. Therefore, there is a possibility of thermal switching in the discharge transistors M6 and M7. Sex is minimized. When the decoded signal is lowered to ground, the voltage of nodes A and B is no longer close to the 20V programming voltage. According to another aspect presented by the present invention, the one shown in FIG. 4 is a multiple parallel transmission transistor controlled by the same node B. M50-M5N drives multiple word line wLO-wLN. There are several situations where this configuration is desired. For example, the actual size of the billion-body array to be remembered may require several block lines for each block. As another example, a high-voltage switch may only be used to program several blocks at the same time. As another example, in a NAND flash memory array, as long as any block in any given NAHD is to be burned, all transmission transistors facing the cell need to be enabled. Depending on the size of the multiple transmission transistors M50-M5H shown in Figure 4, the capacitance CB from node B to ground may be very large, so capacitor C1 must also be large enough to satisfy inequality (1).

Binding of the Central Consumers Bureau of the Ministry of Economic Affairs, Consumer Cooperatives, Printing A7, V. Description of Invention 13) According to another aspect of the present invention, the one shown in FIG. 5 is an embodiment 500 of a clock circuit 500. The clock circuit 500 is commonly used with the high-voltage switch circuit 200 shown in FIGS. 2 and 3. And 300 used. The existence of the clock buffer 500 is based on a switch; therefore, for each high-voltage switching circuit 200 or 300, there is a separate clock buffer 500. The single-phase oscillator signal 0SC can be generated in the chip or externally input. The two-input NAND gate 501 takes the oscillator signal 0SC and the decoded signal DECODE as inputs and generates an inverted clock / CLK signal. The inverter 502 takes an inverted clock signal / CLK as an input and generates a non-inverted clock signal CU as an output. For any high voltage Kailan 20 or 300, as long as the DECODE signal is low, the clock CLK and / CLK oscillations are disabled, so that CLK is statically maintained at ground potential and / CLK is statically maintained at Vcc. Transistors M6 and M7 keep nodes A and B at ground potential. As long as the clocks CLK and / CLK do not oscillate, the high-voltage switches 200 and 300 and the clock circuit 500 do not consume static power. It is a very important fact that the disabled high-voltage switches 200 and 300 and their corresponding clock circuits 500 do not consume static power. This is because there may be a large number of such non-enables in a given programming cycle. Circuit. Figure 6 shows the operation of the embodiment 300 during the charging operation of the present invention. In Figure 6, Vcc is 2 volts and the maximum programming voltage is 20 volts. The oscillator signal 0SC oscillates between 0 volts (ground potential) and 2 volts (V c c) at a period of 60 nanoseconds, as shown in the waveform 601. The high response generator (not shown) needs 1 withdrawal second (1000 nanoseconds) before Vpp (please read the precautions on the back before filling out this page) _installation · d This paper size applies Chinese National Standard (CNS) A4 specifications (210X297 mm) 13 9 1474 Employees' Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs, India and India A7 B7 V. Description of the invention (14) Increase from ground potential to 20 volts. V p p is shown in the waveform 602. Block line output OUT 603 is shown as waveform 603. The waveform 604 in FIG. 6 is the voltage of the node B during the programming operation. At time t1, the DEC 0DE signal rises to a high level, thus causing nodes A and B and the output OUT to rise. During the low phase of the clock CLK, transistor M2 connects node B to Vpp. At the rising edge of CLK, the capacitive connection starts to charge node B to Vpp + Vcc * Cl / (Cl + CB), but the piezoelectric crystal M4 connection discharges node B to Vpp + VtM4. When the charge pump increases the voltage of Vpp and node B, the bulk effect will increase the threshold voltage VtM4 of transistor M4. Therefore, the difference between the voltage Vpp + Vcc * C1 / (Cl + CB) immediately after the rising edge of CLK and the voltage Vpp + VtM4 immediately before the end of the falling edge of CLK will decrease as Vpp increases. The result shown in FIG. 6 is the simulation result of the embodiment shown in FIG. 3. The size of the transistor and the clock frequency should be selected so that the output 0ϋΤ and the node A can follow the change of V ρ ρ during the high phase of C L K, and the node B can follow the change of Vpp during the low phase of CLK. For example, transistor M2 must be large enough for Node B to be charged to Vpp during the high phase of CLK. In the embodiment simulated by the circuit according to the present invention in FIG. 6, the word line 603 installed at the output terminal OUT has 2 picofarad capacitors to ground. Capacitance Cl is 0.2 full Farad and C2 is only 0.1 full Farad. The transmission transistor M5 has a channel width of 10 decimeters and a channel length of 1.2 decimeters. The boost transistor H1 has a channel depth of 4 microns and a channel length of 1.2 metre. The boost transistor M2 has a channel width of 3 Cherm and a channel length of 1.2 Cherm.

Invention Description (16) To BLn, the potential of the cell transistor can be set steadily depending on whether data is written in the cell transistor. When a line and a line are selected from the lines WU to lih and BL! To BLj, respectively When the bit line is selected, a single unit cell cell crystal is selected. To be clear, the cell Cmn at the intersection of the selected block line WLm and the selected bit line BLn is the selected cell. The data value stored in the cell transistor C «n is" 0 ", which means that the cell transistor Cmn is" turned off "and the selected bit line BLn is maintained at VCC because it is raised by the resistor R2n. Otherwise, If the data value stored in the cell transistor Cmn is "1", it means that the cell transistor C «n is" on "and the The selected bit line BLn is pulled down to a lower voltage by the cell transistor Cmn. Then the potential of the bit line BLn is read out by the sense amplifier in the amplifier / input buffer block 28 as the cell information.

The device has a high voltage (Vpp) detector 21, a state control circuit 22, a programming / erasing voltage switch 23, an input / output buffer 24, and X -Decoder 26, Y-decoder 25, Y-gate 27, and amplifier / input buffer 28, the buffer 28 includes a sense amplifier for reading data values stored in the cell transistor The high-voltage (Vpp) detector 21 judges whether there is a high-voltage Vpp. If there is a high-calendar Vpp, the pressure detector outputs a "high" signal V hh to the state control circuit 2 2. If not, it outputs a "low" Signal Vhh. In addition to receiving the signal Vhh by the high-voltage detector 21, the state control circuit 22 also receives the chip enable signal CE /, the write enable signal WE /, and the output enable signal OE / from the outside.

Description of the invention (17) The response of the state control circuit 22 to these signals includes output control signal 0 /, input control signal 1 /, erase signal E / , Write control signal W /, and read signal R /. For example, when the read mode is determined, the state control circuit 22 receives the chip enable signal CE / of the “low”, the output enable signal 0E / of the low j, and the write enable signal WE / of the high j. At the same time, the voltage signal Vhh is "low bit j, which means that the high voltage Vpp is not turned on. Next, the state control circuit 22 provides a" low bit "output control 0 / and captures the R / signal. The lower R / signal enables reading of the contents of the cell array 700; the lower 0 / signal allows the input / output buffer 24 to drive the output pins of the device 800 (not shown). When the write mode is selected, the state control circuit 22 receives "the electrical signal Vhh of the high j and the output enable signal 0E / of the high j." The voltage signal Vhh of the high j indicates that there is a high voltage Vpp; the high output The enable signal 0E / I / O buffer block 24 drives the output pin of the device 8 00 (not shown in the figure). At the same time, the crystal enable signal CE / and the writer pseudo-signal WE / are “low”. Next, the state control circuit outputs the "low" input control signal 1 / and the "low j write signal W /." When the erase mode is selected, the external circuit (not shown) cuts the chip enable signal CE / Can be "high", output enable signal 0E / disable to "high", write enable signal WE / enable to "low". The result is that Vhh rises to a high level, indicating that there is a high voltage Vpp, and then the state control circuit 22 enables "the erasing signal E / of the lower j. When the burn / erase voltage switch 23 receives the" lower j erasing When the signal is E /, the power supply voltage of the cell array 7 00 is cut to a high voltage Vpp. When the "low" erasing signal E / or the paper size is applicable to the Chinese National Standard (CNS) Λ4 specification (210X297 mm) 1 η 9 1474 (诮 Please read the notes on the back before filling in this page)-Printed by the Central Standards Bureau of the Ministry of Economic Affairs, Printed by the Consumers Cooperative of A7 B7 V. Description of the invention (18) The "low" write signal W / is sent When the programming / erasing voltage switch 23 is entered, the switch 23 cuts the output voltage VPER to a high voltage Vpp. VPER is sent to Y-decoder 25. When the input / output buffer 2 4 detects the falling edge of the control signal I / transition from high to low, the input / output buffer 2 4 will receive the input data D0 from the external device (not shown) -D7 hold it. Then the input data D0-D7 will be transferred to the cell array 700 via the lines DI0-DI7. Conversely, when the output control signal 0 / falling edge is received, the balancer 24 will lock the output data D00-D07 from the cell array Hold, and then output the data to external devices via the two-way lines D0-D7. The X-decoder is configured to receive the address signal Am U = 0 to 9), the write signal W /, the read signal R /, and the erase signal E /. In response to these inputs, the X-decoder 25 outputs a selection signal to the cell array to select the desired block line WLb by sending a "high j signal to the block line WLra. The Y-decoder is configured to receive an address Signal An (η = 10 to 16), write signal W /, read signal R /. In response to these inputs, the 解码 -decoder 25 outputs a one-bit line control signal CLn to Υ -gate 27. Υ -gate 27 The bit line BLn is selected to read and write data corresponding to the bit line control signal CLn. More specifically, in the write mode (ie, when the write signal W / is "low"), the high voltage Vpp is Send to the selected bit line BLn. Then, the input data DI is sent from the buffer area 24 to the bit line. In the read mode (ie, when "the low-order j read signal R / is sent to the Y-gate 27), the selected bit line BLn is connected to the sense amplifier in the buffer 28. Then the cell information is determined by The sense amplifier in the buffer 28 is output as the output data D0. 丨 ~ Ί. 丨 ~ ---------------------------- (Please read the precautions on the back first (Fill in this page) This paper size is applicable to China National Standard (CNS) A4 (210X297 mm) 18 91474 Yinzi A7 B7, Shellfish Consumer Cooperative of Central Standards Bureau of the Ministry of Economic Affairs 5.
