Abstract
A Static Random Access Memory (SRAM) comprises an input/output pin and driver means connected to the input/output pin. The driver means are configured to drive the input/output pin to a voltage potential using a first current, and are further configured to hold the input/output pin at approximately the voltage potential using a second current. In one embodiment, the driver means may comprise a driver unit for driving the input/output pin to the voltage potential, a bus hold circuit for holding the input/output pin at the voltage potential and a control unit connected to the driver unit and the bus hold circuit. The control unit may activate and deactivate the driver unit and the bus hold circuit.
