Wide Temperature Range Version 4M High Speed SRAM (256-kword × 16-bit)
ADE-203-1263A (Z) Rev. 1.0 Nov. 1, 2001 Description
The HM62W16255HCI is a 4-Mbit high speed static RAM organized 256-kword × 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. The HM62W16255HCI is packaged in 400-mil 44-pin SOJ and 400-mil 44-pin plastic TSOPII for high density surface mounting.
