Abstract
A portable information handling system solid state storage device monitors thermal conditions to more accurately track program/erase cycles. The program/erase count maintained by the solid state drive is adjusted upward or downward as deviations from a threshold thermal condition warrants.
Claims20
A portable information handling system comprising:
- a housing;
- a processor disposed in the housing and operable to execute instructions to process information;
- a memory disposed in the housing and interfaced with the processor, the memory operable to store the information;
- a solid state storage device disposed in the housing and having flash memory;
- a controller integrated with the solid state storage device and operable to coordinate reads and writes of information to the flash memory, the controller tracking flash memory life based at least in part on a program/erase value;
- a temperature sensor disposed in housing and operable to detect thermal conditions proximate the solid state storage device;
- a chipset operable to coordinate interactions between the processor, memory and controller;
- and
- a program/erase log integrated in the solid state storage device and storing a program/erase value adjusted for thermal conditions sensed by the temperature sensor.
6 more elements
A method for managing storage device life at a portable information handling system, the method comprising:
- monitoring the number of program/erase cycles of a storage device in a program/erase log stored on the information handling system;
- monitoring temperatures proximate the storage device;
- and
- adjusting the number of program/erase cycles in the program/erase log based upon the temperatures.
1 more element
A solid state storage device comprising:
- flash memory operable to persistently store information;
- a controller interfaced with the flash memory and operable to read and write information at the flash memory;
- a temperature sensor interfaced with the controller and operable to detect thermal conditions proximate the flash memory;
- and
- a program/erase log interfaced with the flash memory and storing a program/erase value related to remaining flash memory life;
- wherein the controller is further operable to adjust the program/erase value based on the thermal conditions.
