Abstract: A disclosed method for improving latency or power consumption may include (i) receiving, at a power-state processing circuit, a power-state signal indicating whether a processing unit is entering a low-power-state, (ii) transmitting, in response to the power-state signal indicating that the processing unit is entering the low-power-state, a control signal from the power-state processing circuit to a latching circuit, and (iii) storing, by the latching circuit and in response to the control signal, a state of an input/output pad that is coupled to the processing unit. Various other apparatuses, systems, and methods are also disclosed.
