NONVOLATILE MEMORY ERASURE METHOD AND DEVICE

摘要

Disclosed are non-volatile memory erasure method and device for solving the problem of unnecessary time expenditure and complex process of the current erasure operation. The method comprises: after receiving an erasure instruction, performing a pre-reading verification on the target erasure area corresponding to the erasure instruction; if the pre-reading verification passes, then performing an erasure operation on the target erasure area; if not, then performing pre-programming verification on the target erasure area, and after the pre-programming verification passes, performing the erasure operation on the target erasure area. The method of the present application can eliminate the unnecessary pre-programming verification process while ensuring the target erasure area is in a full-erasure state before the erasure operation, thus saving erasure time and simplifying the erasure process.

1. A non-volatile memory erasure method, wherein, the method comprises:
after receiving an erasure instruction, performing pre-reading verification on a target erasure area corresponding to the erasure instruction; if the pre-reading verification passes, then performing an erasure operation on the target erasure area; and if the pre-reading verification fails, then performing pre-programming verification on the target erasure area, and after the pre-programming verification passes, performing the erasure operation on the target erasure area.
