Description

The HM621400HC is a 4-Mbit high speed static RAM organized 4-Mword × 1-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 and high density memory,

such as cache and buffer memory in system. The HM621400HC is packaged in 400-mil 32-pin SOJ for high

density surface mounting.

Features

• Single 5.0 V supply: 5.0 V ± 10 %

• Access time: 10 ns (max)

• Completely static memory

 No clock or timing strobe required

• Equal access and cycle times

• Directly TTL compatible

 All inputs and outputs

• Operating current: 140 mA (max)

• TTL standby current: 40 mA (max)

• CMOS standby current: 5 mA (max)

: 1.2 mA (max) (L-version)

• Data retension current: 0.8 mA (max) (L-version)

• Data retension voltage: 2 V (min) (L-version)

• Center VCC and VSS type pinout
