- Two standard-cell based memories (SCMs) for op- eration in the subthreshold (sub-VT) region are presented. The SCMs accomplish the task of robust sub-VT storage and fill the gap of missing sub-VT memory compilers. The storage elements (latches) of these SCMs are custom-designed cells using a dual- VT approach to balance timing. Additionally, two read-logic styles are presented: 1) a segmented 3-state implementation that increases performance compared to a pure 3-state implemen- tation; and 2) a purely MUX-based implementation with the 1st stage (NAND gate) integrated into the storage cell. Silicon measurements of two 4kb SCMs manufactured in a low-power 65 nm CMOS technology show that read access speed increases by 4X and 8X compared to a pure 3-state implementation for the segmented 3-state and integrated NAND, respectively, while bit-access energy only increases by 2.7X and 2X to 39 and 29 fJ, respectively.
