ENHANCED CHIP-KILL SCHEMES BY USING SUB-TRUNK CRC

摘要

Memory systems may include a memory storage, and a controller suitable for, receiving a plurality of codewords, each codeword including a user bits portion divided into a number of sub-trunks, determining whether a codeword in the plurality of codewords is decidable, identifying a location of an erroneous sub-trunk in a codeword determined to be undecodable, and recovering the erroneous sub-trunk by summing sub-trunks of other codewords that have a location in their respective codewords that is the same as the location of the erroneous sub-trunk.

1. A memory system, comprising:
a memory storage; and a controller suitable for:
receiving a plurality of codewords, each codeword including a user bits portion divided into a number of sub-trunks;determining whether a codeword in the plurality of codewords is decodable;identifying a location of an erroneous sub-trunk in a codeword determined to be undecodable; andrecovering the erroneous sub-trunk by summing sub-trunks of other codewords that have a location in their respective codewords that is the same as the location of the erroneous sub-trunk.
