Abstract: An apparatus includes a capacitor and logic to adjust an operating temperature of the capacitor according to a charge on the capacitor, and/or to adjust a charge of the capacitor according to the operating temperature of the capacitor to improve the useful life of the capacitor and increase its reliability.

Abstract: An apparatus includes logic to determine a discharge drop of a capacitor and to adjust an enablement charge level of the capacitor according to the discharge drop.

Abstract: A memory subsystem includes a volatile memory and a nonvolatile memory. A controller includes logic to interface the volatile memory to an external system, so that the volatile memory is addressable for reading and writing by the external system. The controller includes logic to back up data from the volatile memory to the nonvolatile memory upon receiving a backup signal from the external system. A power controller includes logic to detect when power from the external system fails, and when power from the external system fails, to provide backup power for long enough to enable the controller to back up data from the volatile memory to a first region of the nonvolatile memory. The controller, upon receiving the backup signal from the external system, backs up data from the volatile memory to a second region of the nonvolatile memory different that the first region used to back up data from the volatile memory to the nonvolatile memory when power from the external system fails.
