Abstract
The embodiments described herein methods and devices that enhance the endurance of a non-volatile memory (e.g., flash memory). The method includes obtaining, for each of the plurality of die, an endurance metric. The method also includes sorting the plurality of die into a plurality of die groups based on their corresponding endurance metrics, where each die group includes one or more die and each die group is associated with a range of endurance metrics. In response to a write command specifying a set of write data, the method further includes writing the write data to the non-volatile memory by writing in parallel subsets of the write data to the one or more die assigned to a single die group of the plurality of die groups.
