Increased Size And Bandwidth Mark New Multi-Port Memories

LANs, WANs and other types of networking systems requiring higher memory capacity and bandwidth have two new candidates for the job in the MCM63D736 4-Mb and MCM63D836 8-Mb dual-port NetRAMs. Representing the latest additions to the company's family of multi-port memories, the new NetRAMs have 36-bit data ports, which are said to provide networks with much higher bandwidth performance compared to conventional small dual-port devices.
The dual I/O devices are designed to enable data to flow more quickly, while their synchronous design allows users to concurrently perform reads, writes and in some cases pass-through cycles on the two data ports. The128Kx36 MCM63D736 is a single-clock, 3.3V, 176 TQFP NetRAM priced at $40 each/10,000, while the 256Kx36 MCM63D836 is a single- or dual-clock, 3.3V, 209-pin MAPBGA memory costing $80.
