Abstract
An integrated circuit (IC) includes a plurality of volatile memory (VM) blocks, and a power gate control circuit configured to control power gating for each VM block of a plurality of VM blocks. The IC includes a power mode controller circuit configured to select a power mode, and in response to selecting a retention mode as the power mode, the power mode controller circuit gates a supply voltage from each block of a selected subset of the plurality of VM blocks and allows a retention voltage to power each VM block of a remaining subset of the plurality of VM blocks outside the selected subset. The IC includes a voltage controller circuit configured to determine a voltage level of the retention voltage based on a minimum retention voltage required for each VM block of the remaining subset.
