Abstract
Systems and methods for balancing multiple partitions of non-volatile memory devices are provided. Embodiments discussed herein execute a balance proportion scheme in connection with a NVM that is partitioned to have multiple partition types. Each partition type has an associated endurance that defines an average number of program/erase (P/E) cycles it can endure before it reaches failure. For example, a first partition type may have a substantially greater endurance than a second partition type. The balance proportion scheme ensures that, even though each partition type has a different associated endurance, all partition types are used proportionally with respect to each other to balance their respective P/E cycles. This way, both partition types will reach the upper limits of their respective endurance levels out at approximately the same time.
