Abstract: A memory system includes memory modules having a number of sets of memory devices including data memory devices for data and error correction code (ECC). The ECC memory devices carry ECC symbols for the memory modules. A host receives and decodes the ECC symbols and executes error correction operations. The host and the memory modules are coupled by a number of channels.

Abstract: A memory system includes memory modules having a number of sets of memory devices including data memory devices for data and error correction code (ECC). The ECC memory devices carry ECC symbols in order to facilitate Redundant Array of Independent Memory (RAIM) functionalities for the memory modules. A host receives and decodes the ECC symbols and executes RAIM operations. The host and the memory modules are coupled by a number of channels, one channel per each set of the memory devices.
