HM6216255H - Hitachi Semiconductor

HM6216255H 4M high Speed SRAM (256-kword x 16-bit)

The HM6216255H 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 (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 configura.
