Abstract
The storage device that includes a non-volatile memory with a control circuitry that is communicatively coupled to an array of memory cells that are arranged in a plurality of word lines. The control circuitry is configured to program the memory cells in a plurality of programming loops. The programming loops include applying a programming pulse to a selected word line of the plurality of word lines. The programming loops also include applying a verify pulse Vto the selected word line to simultaneously verify a lower tail of the memory cells being programmed to a data state N and an upper tail of the memory cells that have been programmed to a data state N−1. The data state N−1 has a lower voltage threshold than the data state N.
