Cache-Only Memory Architecture

A Cache-Only Memory Architecture design (COMA) may be a sort of Cache-Coherent Non-Uniform Memory Access (CC- NUMA) design. not like in a very typical CC-NUMA design, in a COMA, each shared-memory module within the machine may be a cache, wherever every memory line incorporates a tag with the line’s address and state. As a processor references a line, it transparently brings it to each its non-public cache(s) and its near portion of the NUMA shared memory (local memory) – probably displacing a sound line from its native memory.
