Abstract
An SRAM having two capacitors connected in series between respective bit storage nodes of each memory cell. The two inverters of the memory cell are powered by a positive voltage and a low voltage. The two capacitors are connected to each other at a common node. A leakage current generator is coupled to the common node. The leakage current generator supplies to the common node a leakage current to maintain a voltage which is approximately halfway between the voltages of the high and low SRAM supplies.
