Description
The HM62W8511HC is a 4-Mbit high speed static RAM organized 512-kword × 8-bit. It has realized high speed access time by employing CMOS process (6-transistor 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 HM62W8511HC is packaged in 400-mil 36-pin SOJ for high density surface mounting.
