Description

The HM62W4100H is a 4-Mbit high speed static RAM organized 1-Mword × 4-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 and high

density memory, such as cache and buffer memory in system. The HM62W4100H is packaged in 400-mil

32-pin SOJ for high density surface mounting.
