tear preservation encoding

Abstract

Various embodiments relate to a method and system for encoding data to be stored in a memory, comprising: encoding the data to be stored in the memory as first encoded data using an error detection code (EDC) capable of detecting up to 4 bits of error; determining a Hamming weight for the first encoded data; inverting the determined Hamming weight; concatenating the first encoded data and three copies of the inverted Hamming weight into concatenated data; encoding the concatenated data as second encoded data using an error correction code (ECC) capable of correcting 1 bit of error; and storing the second encoded data in the memory.
