A 5 V-only 64K dynamic RAM based on high S/N design

A 5 V-only 64K dynamic RAM is designed and fabricated using double poly-Si technology based on the 3 /spl mu/m design rule. The design features of this dynamic RAM are described. In particular, memory cell and S/N (signal/noise) designs are focused of a dynamic RAM with an on-chip bias generator. The device fabricated provides a typical access time of 120 ns and a 170 mW operating power, with minimized sense noise of less than 50 mV.
