Uniform Memory Access

Uniform Memory Access ( UMA) is generally for a storage architecture in multi-processor systems. There is only one global memory that can be accessed uniformly by all processors on the. Ideally, each having the same bandwidth and latency, and therefore such a system also symmetric multiprocessor system (SMP) is called.

The concept is in contrast to NUMA, wherein the access time depends on the memory of the location of the memory.

Demarcation

The popular in notebooks shared memory graphic is called a Unified Memory Architecture. However, it comes to a collapsed because of space or cost and memory - in contrast to uniform memory access - not to the sharing of memory contents.
