Abstract
A solid state drive (SSD) includes a first storage region classified as byte addressable NV storage region and a controller communicatively coupled to the first storage region by a bus. The controller detects a reduced storage capacity of the first storage region, and in response to the detection, reclassifies the first storage region as a block addressable NV storage region. The SSD dynamically changes byte addressable NV storage regions to block addressable NV storage regions as the byte addressable NV storage regions are degraded, thereby extending the longevity of the SSD.
Claims20
A solid state drive (SSD) enabled to dynamically change byte addressable storage regions to block addressable storage regions, the SSD comprising:
- a first storage region classified as a byte addressable storage region;
- a controller communicatively coupled to the first storage region by a bus, the controller configured to:
- determine a number of data errors in the first storage region that exceed a threshold;
- and
- in response to the determination, reclassify the first storage region as a block addressable storage region.
A method for extending the life of a solid state drive (SSD) including a first storage region and a controller communicatively coupled to the first storage region, the method including:
- determining, by the controller, a number of data errors in the first storage region that exceed a threshold;
- and
- in response to the determination, reclassifying, by the controller, the first storage region as a block addressable storage region.
