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).
