Abstract

Systems and methods for implementing adaptive memory layers in a storage system are disclosed. A storage system may include a non-volatile memory with memory cells configurable to each of a plurality of bit-per-cell capacities and divided into dynamically re-sizable memory layers defined by memory cells of a particular capacity. A memory layer adjustment module associated with a controller of the storage system is configured to, upon detection of a maintenance trigger, compare the amount of valid data and overprovisioning in each layer to a target amount and to redistribute valid data and physical capacity among the memory layers according to a predetermined table or algorithm in order to optimize performance of each memory layer.
