A semiconductor device includes an interface configured to receive clock signals and data signals. The interface includes a dual-tail latch. The dual-tail latch includes a sensing stage configured to sense and to amplify a differential voltage between at least a portion of the data signals and another signal. The sensing stage includes a first node and a second node between which the amplified differential voltage is output from the sensing stage. The dual-tail latch also includes a latch stage configured to latch a first latched value and a second latched value based at least in part on the amplified differential voltage. Moreover, the differential voltage is based at least in part on a previous first value and a previous second value from the latch stage fed back to the sensing stage.

Systems and methods for improved dual-tail latch with load control

A semiconductor device includes a first sensing stage configured to sense a voltage differential of a data signal and a reference signal and output a first amplified voltage differential, wherein the first amplified voltage differential includes a first voltage at a first output node and a second voltage at a second output node. The semiconductor device further includes a second sensing stage configured to sense the first amplified voltage differential and output a second amplified voltage differential, where the second amplified voltage differential includes a third voltage at a third output node and a fourth voltage at a fourth output node. A first power gating circuit is coupled to the third output node and a second power gating circuit is coupled to the fourth output node.
