Description

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. HM62W16255HI 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 44-pin SOJ and 400-mil 44-pin plastic TSOPII.
