Description
The IBM0164165B/P is a dynamic RAM organized
4,194,304 words by 16 bits. This device is fabricated
in IBM’s most advanced CMOS silicon gate process
technology. The circuit and process design allow
this DRAM to achieve high performance and low
power dissipation. The IBM0164165B/P operates
with a single 3.3 ± 0.3V power supply, and inter-
faces directly with eitherTTL orCMOS levels. The 22
addresses required to access any bit of data are
multiplexed (13 are strobed with RAS, 9 are strobed
with CAS). They are packaged in a 50 pin plastic
TSOP type II (400mil×825mil). TheIBM0164165P
parts are low power devices supporting Self Refresh
and a 128ms retention time.
