AMPIC DRAM SYSTEM

摘要

An apparatus for and method of enhancing the performance of a multi-port internal cached DRAM (AMPIC DRAM) and the like by providing an internal meth od of data validation within the AMPIC memories themselves to guarantee that on ly valid requested data is returned from them, or properly marked invalid data; and a modified technique for identifying bad data that has been read out of AMPIC memory devices in the system.
