Abstract
Embodiments of the disclosed technology relate to the operation of memory devices, and more particularly to sub-block mode (SBM) pre-charge operation sequences. One example embodiment provides a novel logic design of the control circuitry of a memory device using comments/instructions for the control circuitry. By virtue of the features of the disclosed technology, the control circuitry can effect pre-charging of an inner or middle vertical sub-block of a NAND string in a memory array. In some examples the NAND string has at least three vertical sub-blocks of non-volatile memory cells.
