Patent ID: 11775381

Abstract:
A plurality of codewords are programmed to one or more memory pages of a memory sub-system. Each memory page of the memory sub-system is associated with a logical unit of a plurality of logical units of the memory sub-system and at least one of a plane of a plurality of planes of the memory sub-system or a block of a plurality of blocks of the memory sub-system. Each codeword of the plurality of codewords comprises host data and base parity bits. A plurality of additional parity bits are programmed to the one or more memory pages of the memory sub-system, wherein each additional parity bit of the plurality of additional parity bits is associated with a codeword of the plurality of standard codewords. A first set of redundancy metadata is generated corresponding to each of the additional parity bits. The first set of redundancy metadata is programmed to a memory page separate from any memory page storing the additional parity bits.
