Description

The HM628511HCI Series is a 4-Mbit high speed static RAM organized 512-k word

× 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. It is

packaged in 400-mil 36-pin plastic SOJ.
