Description
The IBM01644F5B is a dynamic RAM organized
16,777,216 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 IBM01644F5B device oper-
ates with a single 3.3
±
0.3V power supply, and
interfaces directly with either TTL or CMOS levels.
The 24 addresses required to access any bit of data
are multiplexed (13 are strobed with RAS, 11 are
strobed with CAS). They are packaged in a 32 pin
plastic TSOJ (400mil
×
825mil).
