Description
The IBM0165805B/P is a dynamic RAM organized
8,388,608 words by 8 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 IBM0165805B/P operates
with a single 3.3 ± 0.3V power supply, and inter-
faces directly with either LVTTL or LVCMOS levels.
The 23 addresses required to access any bit of data
are multiplexed (12 are strobed with RAS, 11 are
strobed with CAS). They are packaged in a 32 pin
plastic SOJ (400mil×825mil), and a 32pin plastic
TSOP type II (400mil×825mil).The IBM0165805P
parts are low power devices supporting Self
Refresh and a 256ms retention time.
