Title: Method for erasing contents of memory, and memory array for performing the method
Inventor: TARBOURIECH JEAN-CLAUDE
IPC: G11C7/20
Filed: 2000-09-05
Abstract: PROBLEM TO BE SOLVED: To provide a means erasing contents of a RAM without requiring a remarkably large transistor and without causing current spike by adopting advanced erasing operation for each row. SOLUTION: Referring to Fig.4 and 5, advanced row erasion is realized by adding a transistor 72 to a row RAMWIPE transistor (e.g. transistor 69) in each row in series. The transistor 72 is gate-controlled by a signal PRS (preceding row selection). Only when a preceding row also in an array is made SELECTION or ENABLE, PRS of a specific row is made ASSERT or ENABLE. Only when both of the RAMWIPE signal and the PRS(preceding row selection) signal are asserted, a specific row is selected and erased in erasing operation. Therefore, the next row is not erased until the preceding row is erased.
