Abstract:
Methods, devices and systems for a back gated static random access memory (SRAM) cell are provided. One method embodiment for operating an SRAM cell includes applying a potential to a back gate of a pair of cross coupled p-type pull up transistors in the SRAM during a write operation. The method includes applying a ground to the back gate of the pair of cross coupled p-type pull up transistors during a read operation. The charge stored on a pair of cross coupled storage nodes of the SRAM is coupled to a front gate and a back gate of a pair of cross coupled n-type pull down transistors in the SRAM during the write operation and during a read operation.
