FAST SECURE ERASURE SCHEMES FOR NON-VOLATILE MEMORY

摘要

A method includes, in a memory with multiple analog memory cells, storing one or more data pages in respective groups of the memory cells using a first programming configuration having a first storage speed. Upon receiving a request to securely erase a data page from the memory, one or more of the memory cells in a group that stores the data page are re-programmed using a second programming configuration having a second storage speed that is faster than the first storage speed.
