HM6216255HC Series 4M High Speed SRAM (256-kword × 16-bit) ADE-203-1196 (Z) Preliminary Rev. 0.0 Oct. 31, 2000 Description The HM6216255HC Series is a 4-Mbit high speed static RAM organized 256-k word × 16-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 400mil 44-pin plastic SOJ and 400-mil 44-pin plastic TSOPII. Features • Single 5.0 Vsupply : 5.
