Description

The HM62W8511H is a 4-Mbit high speed static RAM organized 512-kword × 8-bit. It has realized high

speed access time by employing CMOS process (4-transistor + 2-poly resistor memory cell) and high speed

circuit designing technology. It is most appropriate for the application which requires high speed, high

density memory and wide bit width configuration, such as cache and buffer memory in system. The

HM62W8511H is packaged in 400-mil 36-pin SOJ for high density surface mounting.
