A memory device may include one or more memory banks that store data and one or more input buffers. The input buffers may receive command address signals to access the one or more memory banks. The memory device may operate in one of a first mode of operation or a second mode of operation. The one or more input buffers may operate under a first bias current when the memory device is in the first mode of operation or a second bias current when the memory device is in the second mode of operation, and the first bias current may be greater than the second bias current.
