Samsung patents memory clock switching to cut power use
Samsung describes a method where a memory controller lowers the speed of its clock signal when the memory is busy with internal tasks. It switches back to a higher speed once the memory is ready, reducing energy use during idle or busy periods.
In the filing’s own words
In an apparatus, a memory controller, a memory device, and a method for switching frequencies of clock signals to reduce power consumption, when the memory device performs an internal operation according to a command of the memory controller, a frequency of a clock signal of the memory controller is changed. The memory controller switches the frequency of the clock signal to a low frequency according to assertion of a status signal that indicates a busy operation status of the memory device according to the command, and switches the frequency of the clock signal to a high frequency according to de-assertion of the status signal that indicates a ready operation status of the memory device.
