Abstract
A power gating circuit for a memory includes a plurality of header switches, the plurality of header switches comprising: a first transistor having a source tied to an external power supply line; and a second transistor coupled to a drain of the first transistor and having its own drain coupled to an internal voltage line of the memory, wherein the second transistor is structured to be used as a transistor or a diode based on control of a gate of the second transistor; and a selection device coupled to the gate of the second transistor to controllably couple the gate of the second transistor in a first state to the drain of the second transistor for diode operation and in a second state to a second voltage line for transistor operation.
