Description
The HM62W1400H is a 4-Mbit high speed static RAM organized 4-Mword
×
1-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 HM62W1400H is packaged in 400-mil
32-pin SOJ and 400-mil 32-pin TSOP II for high density surface mounting.
