US Patent 10944435 Tearing save encoding

Various embodiments relate to a method and system for encoding data to be stored in a memory, including: encoding the data to be stored in memory with an error detection code (EDC), that can detect up to 4 bit errors, as first encoded data; determining the Hamming weight of the first encoded data; inverting the determined Hamming weight; concatenating the first encoded data and three copies of the inverted Hamming weight as concatenated data; encoding the concatenated data with an error correcting code (ECC), that can correct 1 bit error, as second encoded data; and storing the second encoded data in the memory.
