    摘要: An EEPROM includes an array of memory cell transistors, which is divided into cell blocks each including NAND cell units of series-connected cell transistors. A sense amplifier is connected to bit lines and a comparator. A data-latch circuit is connected to the comparator, for latching a write-data supplied from a data input buffer. After desired cell transistors selected for programming in a selected block are once programmed, a write-verify operation is performed. The comparator compares the actual data read from one of the programmed cell transistors with the write-data, to verify its written state. The write-verify process checks the resulting threshold voltage for variations using first and second reference voltages defining the lower-limit and upper-limit of an allowable variation range. If the comparison results under employment of the first voltage shows that an irregularly written cell transistor remains with an insufficient threshold voltage which is so low as to fail to fall within the range, the write operation continues for the same cell transistor. If the comparison results under employment of the second voltage shows that an excess-written cell transistor remains, the block is rendered "protected" at least partially.

    摘要: A NAND cell type EEPROM has bit lines, each of which is associated with a NAND cell unit including a series array of four memory cell transistors. Each transistor is a MOSFET with a control gate and a floating gate for data storage. The memory cell transistors are connected at their control gates to word lines, respectively. One end of the NAND cell unit is connected through a first select transistor to a corresponding bit line; the other end thereof is connected via a second select transistor to a source voltage. The memory cell transistors and the select transistors are arranged in a well region formed in a substrate. In an erase mode, the bit line voltage, the substrate voltage and the well voltage are held at a high voltage, whereas the word lines are at zero volts. The gate potential of the select transistors is held at the high voltage, whereby the internal electric field of these select transistors is weakened to improve the dielectric breakdown characteristic thereof.

    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: An electrically erasable programmable read-only memory is disclosed which has programmable memory cells connected to parallel bit lines provided above a semiconductor substrate. The memory cells include NAND cell blocks each of which has a series array of memory cell transistors. Parallel word lines are connected to the control gates of the memory cell transistors, respectively. In a data write mode, a selection transistor in a certain NAND cell block including a selected memory cell is rendered conductive to connect the certain cell block to a corresponding bit line associated therewith. Under such a condition, electrons are tunnel-injected into a floating gate of the selected memory cell transistor, and the threshold value of the certain transistor is increased to be a positive value. A logical data is thus written in the selected memory cell transistor. The data in the selected cell transistor is erased by discharging carriers accumulated in the floating gate thereof to its drain or the substrate, so that the threshold value of the certain transistor is decreased to be a negative value.
