Abstract
Systems and methods are provided for controlling a wake-up operation of a memory circuit. The memory circuit may include a first memory cell, a first buffer, first logic circuitry, and first switching circuitry. The first memory cell may be configured to pre-charge in response to receiving a primary sleep signal. The first buffer may be configured to receive the primary sleep signal, generate a delayed primary sleep signal, and provide the delayed primary sleep signal to a second memory cell. The first logic circuitry may be configured to generate a first bit line pre-charge signal for the first memory cell of the plurality of memory cells in response to a looped sleep signal, wherein the looped sleep signal is generated based on the delayed primary sleep signal. The first switching circuitry may be configured to provide power to one or more bit line of the first memory cell in response to the first bit line pre-charge signal.
