Abstract

A circuit includes a series of a first latch circuit, selection circuit, second latch circuit, and pre-decoder. A control circuit, based on a clock signal, outputs control signals to the selection circuit and first and second latch circuits, and, to the pre-decoder, a pulse signal including a first pulse during a first portion of a clock period in response to a read enable signal having a first logical state, and a second pulse during a second portion of the clock period in response to a write enable signal having the first logical state. Based on the control signals, the selection circuit and first and second latch circuits output read and write addresses to the pre-decoder during the respective first and second clock period portions, and the pre-decoder outputs a partially decoded address in response to each of the read address and first pulse, and the write address and second pulse.
