SWITCHES COUPLING VOLATILE MEMORY DEVICES TO A POWER SOURCE

摘要

Example implementations relate to coupling volatile memory devices to a power source. In example implementations, data may be copied from a first volatile memory device on a memory module to non-volatile memory. The first volatile memory device may cease to be powered after data is copied from the first volatile memory device to non-volatile memory. After the first volatile memory device has ceased to be powered, data may be copied from a second volatile memory device on the memory module to non-volatile memory. The second volatile memory device may cease to be powered after data is copied from the second volatile memory device to non-volatile memory.

1. A system comprising:
a first volatile memory device; a second volatile memory device; a first switch connected to the first volatile memory device; a second switch connected to the second volatile memory device, wherein each of the first and second switches, when closed, couples the respective volatile memory device to a power source; and a controller communicatively coupled to the first and second volatile memory devices and the first and second switches, wherein the controller is to:
open the first switch after data is copied from the first volatile memory device to non-volatile memory; andcopy data from the second volatile memory device to non-volatile memory after the first switch is opened.
