Devices and techniques for NAND logical-to-physical table region tracking are described herein. A write request, including a logical page and data to be written at the logical page, is received at a controller of a NAND device. The NAND controller may then establish an entry in a logical-to-physical (L2P) mapping table between the logical page and a physical page of a physical block of the NAND device to which the data is written. Here, the entry may be in a region of the L2P mapping table that is one of multiple regions. An indication of the region may be written in a data structure corresponding to the physical block.
