Clocked SR Latch based on NAND Gate. Circuit is implemented with four NAND gates. If this circuit is implemented with CMOS then it requires 16 transistors. The latch is responsive to S or R only if CLK is high. under the desk cycle

"In computer architecture, clock gating is a popular power management technique used in many synchronous circuits for reducing dynamic power dissipation, by removing the clock signal when the circuit is not in use or ignores clock signal. Clock gating saves power by pruning the clock tree, at the cost of adding more logic to a circuit. Pruning the clock disables portions of the circuitry so that the flip-flops in them do not have to switch states. Switching states consumes power. When not b… " - Nand based clock gating
