NON-VOLATILE MEMORY AND ERASING METHOD THEREFOR, AND COMPUTER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/055832
Kind Code:
A1
Abstract:
Provided in the present disclosure are a non-volatile memory and an erasing method therefor, and a computer system. The non-volatile memory comprises a first area, which needs to be erased, and a second area, which does not need to be erased, wherein the first area and the second area share a substrate. The erasing method comprises: executing an erasing operation on a first area; in response to the cumulative number of erasing operations which are executed on the first area reaching a predetermined number N, executing anti-erasing checking on a second area of a memory, wherein N ≥ 2, and the result of the anti-erasing checking indicates whether the second area is interfered with by the erasing operation; and in response to determining that the second area is interfered with by the erasing operation, executing a repair operation on the second area. By means of the erasing method provided in the present disclosure, the impact of an erasing operation on an area which does not need to be erased can be reduced.
