摘要
A method, apparatus and program storage device that provides an error correction code memory system with a small footprint and byte write operation. A memory controller virtualizes the memory controller interface, multiplexes ECC data onto the same pins as data, and stores replicated ECC data structures interleaved with data in system memory. These mechanisms enable a range of very cost effective small memory subsystems that support ECC operation in a minimum of standard commodity memory devices. ECC encoding is provided to support efficient byte write operations.
