Fractured erase system and method

摘要

Efficient and convenient storage systems and methods are presented. In one embodiment, a fractured erase process is performed in which a pre-program process, erase process and soft program process are initiated independently. Memory cells can be pre-programmed and conditioned independent of an erase command. The initiation of the independent pre-programming is partitioned from an erase command which is partitioned from initiation of a soft-programming command. A cell is erased wherein the erasing includes erase operations that are partitioned from the pre-preprogramming process. In one embodiment, the independent pre-program process is run in the background.

主权项

1. A memory alteration process comprising:
determining if portions of a memory are associated with invalid data; and performing independent pre-programming on portions of the memory associated with the invalid data in which the independent pre-programming is performed before receipt of an erase indication on a cell previously used to store data.
