Abstract:
Described are systems and methods for performing partial block erase operations. An example memory device comprises: a memory array comprising a plurality of memory cells electrically coupled to a plurality of wordlines; and a controller coupled to the memory array, the controller to perform operations comprising: identifying, in a memory device, a block comprising a plurality of memory cells; estimating, in the block, a number of pages having a predefined program state; determining, based on the number of pages having the predefined program state, an erase verify voltage to be applied to the block; causing an erase operation to be performed with respect to the block; and causing an erase verify operation to be performed, using the erase verify voltage, with respect to the block.
