Alternative Bitcells

In this paper, we propose a 9T half-select-free subthreshold bitcell that has 2.05X lower mean read energy, 12.39% lower mean write energy, and 28% lower mean leakage current than conventional 8T bitcells at the TT_0.4V_27C corner. Our bitcell also supports the bitline interleaving technique that can cope with soft errors.

In this project, 5T and 6T cells that use asymmetric sizing and single-ended read to achieve better trade-offs between noise margins, power, performance, and area. A new pseudo differential sensing scheme for single-ended cells is also explored.
