Abstract
A system for improving the management and usage of blocks based on intrinsic endurance may be used to improve memory usage for flash memory, such as a memory card. The overall card endurance may be extended by cycling blocks with higher intrinsic endurance over the lowest endurance target of the worst block. This may be accomplished by managing blocks with different intrinsic endurance values internally or by partitioning the blocks with different intrinsic endurance values externally for different usage.
