Title: Semiconductor Storage Device and Production Method Thereof
Inventor: ISHIGE KIYOKAZU
IPC: H01L21/8247
Filed: 2000-11-28
Abstract: PURPOSE: To quickly and completely erase data in a group of memory cells in a semiconductor storage that uniformly executes data erasure until an entire cell threshold is set to standard value or less with the group of memory cells, and replenishes, the memory cell with electric change where the cell threshold is set to the minimum one or less in the group of memory cells where data has been erased. CONSTITUTION: When a manufacturing error causing reduction of erasure speed as compared with an ideal value occurs in an extremely small group of memory cells at a group of specific positions, merely the memory cells at a position where the manufacturing error occurs are formed so that the erasure speed becomes faster than the ideal value. When the erasure speed of the extremely small group of memory cells is decreased, erasure becomes excessive at the most part of the group, and replenishment of charge is required, thus increasing the erasure time in the entire group. However, when erasure of merely the extremely small group of memory cells is made at high speed, the erasure is excessive and the replenishment of charge is required in the extremely small group of memory cells, thus quickly completing the data erasure in the group of memory cells.
