Abstract

The invention discloses a method for resetting a nonvolatile memory, comprising: decoding a reset instruction of the nonvolatile memory; judging whether the reset instruction occurs during the erasing of the nonvolatile memory During the erasing operation, if it occurs during the erasing operation, then end the erasing operation; perform over-erasing verification and over-erasing repair operations on the erasing area corresponding to the erasing operation; performing a reset operation on the non-volatile memory; and ending the reset operation on the non-volatile memory. The present invention can eliminate the impact of over-erasing on other areas of the physical storage block where the erased area is located before performing a reset operation on the non-volatile memory, thereby ensuring the correctness and stability of the non-volatile memory.

Description

technical field [0001] The invention relates to the technical field of nonvolatile memory, in particular to a method for resetting the nonvolatile memory. Background technique [0002] Non-volatile memory, also known as non-volatile memory, simply put, is a memory that can retain stored data in the event of power failure. With the development of related technologies of the non-volatile memory, the application of the non-volatile memory becomes more and more extensive. [0003] Non-volatile memory is often accompanied by reset operations such as hardware reset or software reset. These reset operations are asynchronous to other instruction operations of non-volatile memory, that is, non-volatile memory is performing normal programming or erasing. In the process of such operations, it is possible to receive a reset command executed by the user, and the execution of the reset operation needs to end the ongoing programming or erasing operations. If the reset command occurs duri...
