Using spare bits in memory systems

Abstract:

Disclosed is a computer implemented method to mark data as persistent using spare bits. The method includes receiving, by a memory system, a set of data, wherein the set of data includes a subset of meta-bits, and the set of data is received as a plurality of transfers, and wherein the memory system includes a first rank and a second rank. The method also includes decoding, by a decoder, the subset of meta-bits, wherein the subset of meta-bits are configured to indicate the set of data is important. The method further includes storing, based on the decoding, the set of data in a persistent storage medium.
