HM621400H Series
4M High Speed SRAM (4-Mword × 1-bit)
ADE-203-787D (Z)
Rev. 1.0
Sep. 15, 1998
Description
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 and high density
memory, such as cache and buffer memory in system. The HM621400H 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 10/12/15 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: 200/180/160 mA (max)
TTL standby current: 70/60/50 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
