Abstract
Embodiments generally relate to improving reliability of processing cache lines with metadata symbols encoded into parity symbols of codewords. The data and metadata of a cache line are encoded into codewords where each codeword is a number of (1) message symbols, each including message bits from data of the cache line, and (2) parity symbols, each including parity bits determined from the message symbols and a metadata symbol. For each codeword of the cache line, the plurality of message and parity symbols are rotated so that a location of each symbol of one codeword is different from other codewords of the cache line. The codewords of the cache line are then stored in memory as rotated. In this manner, the reliability is improved by rotating symbols of the codewords of the cache line, with metadata symbols encoded into parity of codewords, before storage in memory.
