Abstract
Aspects of the present disclosure provide various apparatus, devices, systems and methods for dynamically configuring a cache partition in a solid state drive (SSD). The SSD may include non-volatile memory (NVM) that can be configured to store a different number of bits per cell. The NVM is partitioned into a cache partition and a storage partition, and the respective sizes of the partitions is dynamically changed based on a locality of data (LOD) of the access pattern of the NVM.
