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 a UMA architecture, access time to a memory location is independent of which processor makes the request or which memory chip contains the transferred data.
Uniform Memory Access computer architectures are often contrasted with Non-Uniform Memory Access (NUMA) architectures.
In the UMA architecture, each processor may use a private cache. Peripherals are also shared in some fashion, The UMA model is suitable for general purpose and time sharing applications by multiple users. It can be used to speed up the execution of a single large program in time critical applications.

Famous quotes containing the words uniform, memory and/or access:
“He may be a very nice man. But I haven’t got the time to figure that out. All I know is, he’s got a uniform and a gun and I have to relate to him that way. That’s the only way to relate to him because one of us may have to die.”
—James Baldwin (1924–1987)
“The best memory is not as good as pale ink.”
—Chinese proverb.
“Oh, the holiness of always being the injured party. The historically oppressed can find not only sanctity but safety in the state of victimization. When access to a better life has been denied often enough, and successfully enough, one can use the rejection as an excuse to cease all efforts. After all, one reckons, “they” don’t want me, “they” accept their own mediocrity and refuse my best, “they” don’t deserve me.”
—Maya Angelou (b. 1928)
