Abstract

Apparatus and method for managing data in a memory, such as but not limited to a flash memory array. In accordance with some embodiments, a soft erasure is performed on a block of memory cells by toggling an erasure status value without otherwise affecting a written state of the cells in the block. The memory cells are subsequently overwritten with a set of data using a write polarity direction determined responsive to the toggled erasure status value.
