Low-voltage, low-power SRAM circuits using subthreshold design technique
This chapter explores the design space of proposed M7T, MPT8T, M8T, M9T and MI-12T SRAM cells implemented at 45 nm technology node which are suitable for subthreshold operation. For quick comparison, Figure 3.45 shows the comparative design space exploration (DSE) chart of SRAM cells at 45 nm technology, respectively. The thorough analyses on the impacts of read stability, write ability, average write delay, average read delay and leakage power consumption in hold mode have been summarized in Table 3.14. The proposed memory cells exhibit improvement in performance over C6T.
