Description
The HM624100H is a 4-Mbit high speed static RAM organized 1-Mword
脳
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 HM624100H is packaged in 400-mil 32-pin SOJ
for high density surface mounting.
