Shared memory
Computer memory that can be accessed by multiple processes / From Wikipedia, the free encyclopedia
In computer science, shared memory is memory that may be simultaneously accessed by multiple programs with an intent to provide communication among them or avoid redundant copies. Shared memory is an efficient means of passing data between programs. Depending on context, programs may run on a single processor or on multiple separate processors.
Computer memory that can be accessed by multiple processes
Using memory for communication inside a single program, e.g. among its multiple threads, is also referred to as shared memory.
