Abstract: Wordline-driver biasing and column-based source-biasing circuitry facilitate reduced current leakage, for example, in SoC device SRAM circuits in a manner that is independent of the read/write/standby operating mode, and without an external trigger. Wordline-driver-biasing circuitry turns off (i.e., decouples from system power) wordline-drivers that are connected to unselected wordlines during read/write operations using one of a decoder-enable signal, which is generated in response to row address values, or based on the activation of a self-timing internal clock, which is generated by the memory circuit when it is activated (i.e., switched from standby to read/write mode). Alternatively, or in addition, source-biasing circuitry applies a relatively high source-biasing voltage to the source terminals of memory cells in unselected columns during read/write operations based on column address values (i.e., a low source voltage is applied only to the selected column being written to or read from).

Abstract: An electronic device comprises a semiconductor memory cell having a bistable bit storage circuit having first and second power contact points. A first switch is coupled to the first power contact point to receive a first voltage. A second switch coupled to the second power contact point to receive a second voltage. Circuitry is provided for turning off the first and second switches to decouple the respective first and second voltages from the respective first and second power contact points, during stand-by operation of the electronic device.
