Abstract: A method for multi-stage programming of a non-volatile memory structure, wherein the method comprises: (1) initiating a programming operation with respect to a memory block, (2) applying a programming algorithm to the memory block, wherein the programming algorithm comprises at least a first programming stage and a second programming stage, and (3) between the first programming stage and the second programming stage, applying a time delay according to a pre-determined amount of time. Further, the pre-determined amount of time may be defined as the amount of time that, according to a probabilistic function, permits de-trapping of any charges unintentionally trapped within a memory cell of the memory block as a result of the first programming stage.

Abstract: Techniques are described for programming memory cells without performing a verify test, where the programming is followed by a short circuit test. In one aspect, an initial programming is performed on memory cells of a first word line of a block using a program pulse with an initial magnitude, Vpgm. By reading the memory cells, Vpgm can be optimized for programming subsequent word lines. The subsequent word lines may be programmed using a no-verify program operation followed by a word line short circuit test, for one or more word lines involved in the program operation. The short circuit test can be performed concurrently on a single word line, multiple word lines and/or one or more sub-blocks of a block, based on an amount of write data which can be storage by a controller.
