HM621400H Datasheet (Hitachi Semiconductor) - 4M High Speed SRAM (4-Mword x 1-bit)

HM621400H, 4M High Speed SRAM (4-Mword x 1-bit)

The HM621400H 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 an
