Abstract
According to some embodiments, it may be determined that a processing system is to transition from a higher-power state to a lower-power state. System information may then be copied from a volatile memory device to a low-latency persistent memory device, and it may be arranged for the processing system to transition from the higher-power state to the lower-power state.
Claims27
A method, comprising:
- determining that a processing system is to transition from a higher-power state to a lower-power state;
- copying system information from a volatile memory device to a persistent memory device;
- and
- arranging for the processing system to transition from the higher-power state to the lower-power state.
1 more element
An apparatus, comprising:
- a processor;
- a volatile memory to store operating system image information when the apparatus is in a higher-power state;
- and
- a persistent memory device to store the operating system image information when the apparatus is in a lower-power state.
1 more element
A computer system, comprising:
- a processor;
- a battery to supply power to the processor;
- a volatile memory to store context information when the computer system is in a first power state;
- and
- a persistent memory device to store the context information when the computer system is in a second power state.
2 more elements
An article, comprising:
- a storage medium having stored thereon instructions that when executed by a machine result in the following:
- determine that a processing system is to transition from a higher-power state to a lower-power state;
- copy system information from a system random access memory to a flash memory;
- and
- arrange for the processing system to transition from the higher-power state to the lower-power state.
