METHOD AND DEVICE FOR MRAM SMART BIT WRITING ALGORITHM BY ERROR CORRECTION PARITY BIT

摘要

PROBLEM TO BE SOLVED: To provide MRAM smart bit writing algorithm by an error correction parity bit.SOLUTION: A method attempts to write an expected multibit word in a storage location of a memory. After the writing of a multibit word is attempted, an actual multibit word is read from the storage location. Then, the actual multibit word is compared with the expected multibit word, and a group of error bits and a group of correct bits saved in the storage location are identified. The group of correct bits is not re-written in the storage location, and the group of error bits is re-written in the storage location.
