Abstract

Systems and methods are provided for dynamically allocating a number of bits per cell to memory locations of a non-volatile memory ('NVM') device. In some embodiments, a host may determine whether to store data in the NVM device using SLC programming or MLC programming operations. The host may allocate an erased block as an SLC block or MLC block based on this determination regardless of whether the erased block was previously used as an SLC block, MLC block, or both. In some embodiments, to dynamically allocate a memory location as SLC or MLC, the host may provide an address vector to the NVM package, where the address vector may specify the memory location and the number of bits per cell to use for that memory location.
