Claims20
A data processing system, the data processing system comprising:
- a soft information correction circuit operable to:
- receive soft information corresponding to a series of voltage levels accessed from a block of memory cells;
- calculate corrected soft information based upon the received soft information and a variance of the soft information.
A method for accessing information from a storage device, the method comprising:
- receiving soft information corresponding to a series of voltage levels accessed from a block of flash memory cells;
- calculating corrected soft information based upon the received soft information and a variance of the soft information;
- and
- applying a data decoding algorithm to the corrected soft information to yield a data output.
