Description
The V53C516405A is a 4,194,304 x 4 bit highperformance CMOS dynamic random access memory. The V53C516405A offers Page mode operation with Extended Data Output. The V53C516405A has a symmetric address, 12-bit row and 10-bit column. All inputs are TTL compatible. EDO Page Mode operation allows random access up to 1024 x 4 bits, within a page, with cycle times as short as 20ns. These features make the V53C516405A ideally suited for a wide variety of high performance computer systems and peripheral applications.
