Secure memory which reduces degradation of data

摘要

A method for managing a non-volatile memory may include a first phase of writing data to a first bank of a memory plane of the non-volatile memory, and then a second phase of writing the same data to a second bank of the same memory plane of the non-volatile memory in the case of success of the first writing phase.

1. A method for operating a non-volatile memory comprising a memory plane having first and second banks of non-volatile memory cells for storing redundant data, the method comprising:
entering a secure writing mode based upon a write opcode; performing a first phase of writing the redundant data to the first bank of the memory plane after entering the secure writing mode; and if the first phase of writing the redundant data is successful, performing a second phase of writing the redundant data to the second bank of the memory plane.
