A memory circuit includes a control circuit coupled to the word line driver circuit. The control circuit is configured to delay a leading or falling edge of a word line signal in response to at least a first clock signal. The control circuit includes a first clock circuit configured to generate a second clock signal in response to a first reset signal and a clock signal, and an adjustable delay circuit configured to adjust a delay between the second and third clock signal in response to the second clock signal and an enable signal. The third clock signal is a delayed version of the second clock signal. An amount of the delay between the second and third clock signal is based on a voltage difference between a first supply voltage having a first swing, and a second supply voltage having a second swing.

Memory circuit and method of operating same

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.
