REDUCING POWER CONSUMPTION OF VOLATILE MEMORY VIA USE OF NON-VOLATILE MEMORY

摘要

A method includes initiating a transition from an operating mode to a sleep mode at an electronic device that includes a volatile memory and a non-volatile memory. In response to the initiating, data is copied from the volatile memory to the non-volatile memory and a portion of the volatile memory is disabled. Another method includes determining that a low performance mode condition is satisfied at an electronic device that includes a volatile memory that stores a first copy of read-only data and a non-volatile memory that stores a second copy of the read-only data. A memory mapping of the read-only data is updated from the volatile memory to the non-volatile memory. A portion of the volatile memory that stores the first copy is disabled and access of the read-only data is directed to the non-volatile memory instead of the volatile memory.

1. A method comprising:
initiating a transition from an operating mode to a sleep mode at an electronic device, wherein the electronic device comprises a volatile memory device having a first size and a non-volatile memory device having a second size that is greater than or equal to the first size; in response to the initiating, copying data from the volatile memory device to the non-volatile memory device; and disabling a portion of the volatile memory device during the sleep mode.
