ADAPTIVE READ AND WRITE SYSTEMS AND METHODS FOR MEMORY CELLS

Adaptive memory read and write systems and methods are provided that may compute estimated means and variances of multi-level memory cells to facilitate writing and reading of data to and from the multi-level memory cells are described herein. The systems may include an apparatus comprising multi-level memory cells, and an estimation block configured to compute estimated means and variances of level distributions of the multi-level memory cells by processing signal samples provided by at least a subset of the multi-level memory cells, the estimated means and variances to be used to facilitate writing and/or reading of data to and/or from at least selected ones of the multi-level memory cells, the multi-level memory cells having M-levels where M is an integer greater than 1, and each of the level distributions is associated with a corresponding level of the M-levels.
