Description

The IBM0117805 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-

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).
