DYNAMIC OVER PROVISIONING ALLOCATION FOR PURPOSED BLOCKS

Abstract:

Write operations are performed to write data to user blocks of the memory device and to write, to a first set of purposed blocks, purposed data related to the first data written at the memory device. Whether the first set of purposed blocks satisfy a condition indicating an endurance state of the first set of purposed blocks is determined. Responsive to the first set of purposed blocks satisfies the condition, one or more blocks from a pool of storage area blocks of the memory device are allocated to a second set of purposed blocks.
