QRAM-Quick access memory system
H. Niijima, Nobuyuki Oba · 2002
A quick access memory (QRAM) was developed that realizes a cost-effective high-performance memory architecture. The QRAM improves the effective data access speed by making maximum use of the page mode of memory, and hence acts like a pseudo-cache memory. For high performance and usability, it has three special features: built-in address latches/comparators, a direct handshake facility, and a multiple active island structure. It can communicate directly with the microprocessor by handshaking of the memory request and the memory ready. This reduces the amount of external logic needed for the memory system. The QRAM can be made with conventional technology.>
