The HYB 514171BJ is a 4 MBit dynamic RAM organized as 262 144 words by 16-bit. The HYB 514171BJ utilizes CMOS silicon gate process as well as advanced circuit techniques to provide wide operation margins, both internally and for the system user. Multiplexed address inputs permit the HYB 514171BJ to be packed in a standard plastic 400 mil wide P-SOJ-40-1 package.
