Abstract

Methods and apparatus for compensating for charge loss in memories include tracking a specific block of the main memory array and determining charge loss compensation by comparing pre-cycled and post-cycled mean threshold voltages for the tracking block; or tracking each block of the main memory and determining charge loss and compensation on a block by block basis.
