Abstract
Rather than having unused die blocks, partial die blocks can contribute to a super block. In so doing, as much of the available physical capacity of the data storage device may be achieved. The result could be an increase in over provisioning (OP) and good capacity for the data storage device or an increase in die yield. An increase in good capacity through the use of previously unused physical blocks would lead to an increase in performance and endurance. A yield increase would result in a reduction in cost per die and per data storage device. A partial die block is the solution.
