Patent number: 7139201Abstract: 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.Type: GrantFiled: October 6, 2005Date of Patent: November 21, 2006Assignee: Kabushiki Kaisha ToshibaInventors: Tomoharu Tanaka, Masaki Momodomi, Hideo Kato, Hiroto Nakai, Yoshiyuki Tanaka, Riichiro Shirota, Seiichi Aritome, Yasuo Itoh, Yoshihisa Iwata, Hiroshi Nakamura, Hideko Odaira, Yutaka Okamoto, Masamichi Asano, Kaoru Tokushige

Patent number: 6081454Abstract: 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.Type: GrantFiled: September 2, 1998Date of Patent: June 27, 2000Assignee: Kabushiki Kaisha ToshibaInventors: Kazunori Ohuchi, Tomoharu Tanaka, Yoshihisa Iwata, Yasuo Itoh, Masaki Momodomi, Fujio Masuoka

Patent number: 5978265Abstract: 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.Type: GrantFiled: August 15, 1991Date of Patent: November 2, 1999Assignee: Kabushiki Kaisha ToshibaInventors: Ryouhei Kirisawa, Riichiro Shirota, Ryozo Nakayama, Seiichi Aritome, Masaki Momodomi, Yasuo Itoh, Fujio Masuoka
