Abstract: In certain aspects, a system comprises a power collapsible logic block, a plurality of retention flip-flops coupled to the power collapsible logic blocks, wherein the plurality of retention flip-flops includes a group of master-slave flip-flops and a group of balloon flip-flops, and a power controller configured to retain states of the group of balloon flip-flops and states of the group of master-slave flip-flops in a first sleep state and to retain the states of the group of balloon flip-flops but not states of the group of master-slave flip-flops in a deep sleep state.
