a) The chips in a computer that contain its working memory. b) Usually used to mean semiconductor read/write memory. Strictly speaking, ROMs are also RAMs. See also Random Access. c) This term has come to mean any semiconductor memory whose write access time is approximately the same as its read access time. This is typically taken to include SRAMs (Static RAMs) and DRAMs (Dynamic RAMs). This definition specifically eliminates memories that cannot be altered at all and memories that require a special fixture for erasing (such as EPROMs).
Industry:Software
A technique for trying an ATV scheme inside a computer without actually building specialized equipment. Some question the validity of ATV simulations.
