Method and apparatus for processing nuisance data

摘要

A memory device having a plurality of nonvolatile memory cells for storing stored data where the stored data includes user stored data and nuisance stored data. A memory controller includes a transmitter for transmitting write data for storage as the stored data in the memory. The transmitter includes a selector for selection of user write data for storage as the user stored data in the memory and for selection of nuisance write data for storage as the nuisance stored data in the memory. The memory controller includes a receiver for receiving the stored data from the memory as read data where the read data includes the user stored data and the nuisance stored data. The receiver includes a Hamming weight detector for detecting the Hamming weights of read data received from the memory for distinguishing user stored data from nuisance stored data.
