Systems, apparatuses, and methods for implementing a low-power, single-pin retention flip-flop with a balloon latch are described. A flip-flop is connected to a retention latch to store a value of the flip-flop during a reduced power state. A single retention pin is used to turn on the retention latch. During normal mode, the retention latch is pre-charged and a change in the value stored by the flip-flop does not cause the retention latch to toggle. This helps to reduce the power consumed by the circuit during normal mode (i.e., non-retention mode). When the retention signal becomes active, the retention latch gets triggered and the value stored by the flip-flop is written into the retention latch. Later, if the flip-flop is powered down and then powered back up while the circuit is in retention mode, the value in the retention latch gets written back into the flip-flop.
