Abstract:
A first logical page type and a second logical page type each comprising a plurality of programming distributions of a memory device are identified. A determination is made that the bit error rate (BER) for the first logical page type is less than a BER for the second logical page type. A set of rules corresponding to a determination that the BER for the first logical page type is less than the BER for the second logical page type is identified. A program targeting rule of the set of rules is determined based on a valley between an erase distribution and a programming distribution adjacent to the erase distribution having a lowest valley margin of a plurality of valley margins corresponding to the plurality of programming distributions of the memory device. Based on the program targeting rule, a program targeting operation is performed to adjust a voltage associated with one or more programming distributions of the memory device.
