摘要： An erasable programmable read-only memory with a NAND cell structure including NAND cell blocks, each of which has a selection transistor connected to the corresponding bit line and memory cell transistors connected is series. Word lines are connected to control gates of the cell transistors. In a data write mode, a selection transistor of a certain cell block containing a selected cell is rendered conductive to connect the cell block to the corresponding bit line. A control circuit is provided for applying an "L" Level voltage (approximately O V) to a word line connected to the selected cell, applying an "H" level voltage (approximately 20 V) to a word line or word lines positioned between the selected word line and a contact node connecting the cell block and a specific bit line associated therewith, applying a voltage corresponding to data to be written to the specific bit line, and applying an intermediate voltage between the "H" and "L" level voltages to non-selected bit lines, thereby writing the data in the selected cell by tunneling. If the data is logic "0" data, the intermediate voltage is applied also to the specific bit line.

摘要： A NAND cell type electrically erasable programmable read-only memory has a memory array section containing NAND cell units. Each NAND cell unit has a series array of floating gate type metal-oxide semiconductor field effect transistors as memory cell transistors. The memory section is associated with a control-gate controller, a data-latch circuit, a sense amplifier section, and a data comparator, which is connected via an output buffer to a verify-termination detector. When a data is once written into a selected memory cell in a data programming mode, a specific biasing voltage is applied to the selected cell so that the actual electrical data write condition of the selected memory cell is verified. If the comparator detects that the verified write condition is dissatisfied, data-rewriting operations are repeatedly executed by additionally supplying the selected cell with a suitable voltage which compensates for the dissatisfaction of the verified write condition in the selected memory cell transistor.

摘要： The time required for the program verify and erase verify operations can be shortened. The change of threshold values of memory cells can be suppressed even if the write and erase operations are executed repetitively. After the program and erase operations, whether the operations were properly executed can be judged simultaneously for all bit lines basing upon a change, after the pre-charge, of the potential at each bit line, without changing the column address. In the data rewrite operation, the rewrite operation is not effected for a memory cell with the data once properly written, by changing the data in the data register.

摘要： An erasable programmable read-only memory with NAND cell structure includes NAND cell blocks, each of which has a selection transistor connected to the corresponding bit line and a series array of memory cell transistors, and a switching transistor connected between the series array of memory cell transistors and ground. Each cell transistor has a floating gate and a control gate. Word lines are connected to the control gates of the cell transistors. In a data writing mode, a selection transistor of a certain cell block containing a selected cell is rendered conductive, so that this cell block is connected to the corresponding bit line. Under such a condition, a decoder circuit stores a desired data (a logic "one" e.g.) in the selected cell, by applying an "H" level voltage to the bit line, applying an "L" level voltage to a word line connected to the selected cell, applying the "H" level voltage to a memory cell or cells positioned between the selected cell and the bit line, and applying the "L" level voltage to a memory cell or cells positioned between the selected cell and the ground. The selection transistor and switching transistor for a corresponding series array of memory cell transistors have different channel lengths to reduce punch through.

摘要： A NOR operation is performed on the address bit by bit by a NOR circuit, and when the final address in a page is detected from the result of the NOR operation by a final address detection circuit, a program starting circuit executes data writing to a memory cell. This can ensure detection of the final address in a page without using a counter circuit. It is therefore possible to simplify the structure of the final address detection circuit and reduce the circuit area occupying in a semiconductor memory device.

摘要： An electrically erasable programmable read-only memory has memory cell blocks, each of which has NAND type cell units associated with the bit lines respectively. Each cell unit has a series-circuit of floating gate type memory cell transistors and a selection transistor provided between the corresponding bit line and the series-circuit of memory cell transistors. A row decoder is provided in common to the memory cell blocks, for generating an "H" level voltage which is supplied to a selection gate control line connected to the selection transistor and to a selected word line or lines in a cell unit. A voltage boost circuit is provided for every memory cell block, for causing the "H" level voltage to increase up to a preselected potential level which is high enough to render the cell transistors conductive. The voltage boost circuit includes a first booster section for the selection gate control line, and a second section for the word lines. The second section operates in response to the output voltage of the first section.
