  2. Uniform memory access - Wikipedia

    en.wikipedia.org/wiki/Uniform_memory_access

    Uniform memory access (UMA) is a shared memory architecture used in parallel computers.All the processors in the UMA model share the physical memory uniformly. In an UMA architecture, access time to a memory location is independent of which processor makes the request or which memory chip contains the transferred data.
