Description
The HM62W4100HC is a 4-Mbit high speed static RAM organized 1-Mword
脳
4-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 and high density memory,
such as cache and buffer memory in system. The HM62W4100HC is packaged in 400-mil 32-pin SOJ for
high density surface mounting.
