Description
The HM62W16255H 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, such as cache and buffer memory in system. The
HM62W16255H is packaged in 400-mil 44-pin SOJ and 400-mil 44-pin plastic TSOPII for high density
surface mounting.
