| description | Apparatus and methods are disclosed, including using a memory controller to partition a memory array into a first portion and a second portion, the first portion and second portion having non-overlapping logical block addressing (LBA) ranges. The memory controller assigns a first granularity of a first logical-to-physical (L2P) mapping table entry for the first portion of the memory array designated for a first usage, and a second granularity of a second L2P mapping table entry for the second portion of the memory array designated for a second usage, where the second granularity is not equal to the first granularity. The memory controller stores the first granularity and the second granularity in the memory array, and stores at least a portion of the first L2P mapping table entry and the second L2P mapping table entry in an L2P cache of the memory controller. |
