A Sub-VT 2T Gain-Cell Memory for Biomedical Applications

All state-of-the-art subthreshold (sub-VT) memories are based on static bitcells, while the feasibility and limitations of dynamic bitcells operated in the sub-VT regime have not been studied yet. For the first time ever, we examine the sub-VT operation of gain-cells and present a fully functional memory array with data retention times that are 10e4X higher than access times.
