HM62W16255HI - Hitachi Semiconductor

HM62W16255HI 4M High Speed SRAM (256-kword x 16-bit)

The HM62W16255HI is a 4-Mbit high speed static RAM organized 256-kword × 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 configuration, s.
