Description
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 21
addresses required to access any bit of data are
multiplexed (11 are strobed with RAS, 10 are
strobed with CAS).
The IBM0117800 is a dynamic RAM organized
2,097,152 words by 8 bits, which has a very low
“sleep mode” power consumption option. These
devices are fabricated in IBM’s advanced 0.5µm
CMOS silicon gate process technology. The circuit
and process have been carefully designed to pro-
