Nov. 30, 2000
Description
The HM624100HC is a 4-Mbit high speed static RAM organized 1-Mword × 4-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 HM624100HC 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 ccurrent : 5 mA (max)
: 1.2 mA (max) (L-version)
Data retension current : 0.8 mA (max) (L-version)
Data retension voltage : 2.0 V (min) (L-version)
Center VCC and VSS type pinout
