Abstract
An apparatus includes memory arrays and a power-performance-endurance manager module. The power-performance-endurance manager module stores a power-endurance state descriptor data structure, which includes endurance levels associated with power-endurance modes. The manager module dynamically configures the apparatus to operate the memory arrays according to one of the power-endurance modes based on a desired endurance level.
Claims20
An apparatus comprising:
- a plurality of memory arrays;
- a power-performance-endurance manager module configured to:
- store a power-endurance state descriptor data structure comprising a plurality of endurance levels associated with a plurality of power-endurance modes;
- dynamically configure the apparatus to operate the plurality of memory arrays according to one of the plurality of power-endurance modes based on a desired endurance level of the plurality of endurance levels;
- tune the apparatus, based on trade-off determinations between endurance operations and power consumptions of the apparatus, to another of the plurality of power-endurance modes respective to another desired endurance level of the plurality of endurance levels.
