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:
“Truly man is a marvelously vain, diverse, and undulating object. It is hard to found any constant and uniform judgment on him.”
—Michel de Montaigne (1533–1592)
“She might have been old once and now, miraculously, young again—but with the memory of that other life intact. She seemed to know the world down there in the dark hall and beyond for what it was. Yet knowing, she still longed to leave this safe, sunlit place at the top of the house for the challenge there.”
—Paule Marshall (b. 1929)
“Power, in Case’s world, meant corporate power. The zaibatsus, the multinationals ..., had ... attained a kind of immortality. You couldn’t kill a zaibatsu by assassinating a dozen key executives; there were others waiting to step up the ladder; assume the vacated position, access the vast banks of corporate memory.”
—William Gibson (b. 1948)
