Description
The IBM0117405 is a dynamic RAM organized
4,194,304 words by 4 bits, which has a very low
“sleep mode” power consumption option. These
devices are fabricated in IBM’s advanced 0.5
μ
m
CMOS silicon gate process technology. The circuit
and process have been carefully designed to pro-
vide high performance, low power dissipation, and
high reliability. The devices operate with a single
3.3V
±
0.3V or 5.0V
±
0.5V power supply. The 22
addresses required to access any bit of data are
multiplexed (11 are strobed with RAS, 11 are
strobed with CAS).
