摘要
A power management controller controls a power mode associated with a memory device and includes a logic element operative to provide a power mode control signal. The logic element is responsive to first and second control signals, the second control signal being a delayed version of the first control signal. The first control signal is provided by a processing device, and the power mode control signal transitions (i) inactive before a chip select signal transitions active and/or (ii) active after the chip select signal transitions inactive. The chip select signal controls the memory device, and the power mode control signal controls the power mode associated with the memory device. A corresponding method, computer-readable medium, and electronic system are also disclosed. A method that selects a power control mode associated with the power management controller, which controls a power mode associated with the memory device, is also disclosed.
