4M High Speed SRAM (512-kword × 8-bit)
ADE-203-1197 (Z)
Preliminary
Rev. 0.0
Nov. 9, 2000
Description
The HM628511HC Series is a 4-Mbit high speed static RAM organized 512-k word × 8-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, high density
memory and wide bit width configuration, such as cache and buffer memory in system. It is packaged in 400-
mil 36-pin plastic SOJ.
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
