Abstract
The memory device includes a memory block with a plurality of memory cells that are arranged in a plurality of word lines and a plurality of NAND strings, which are coupled to a plurality of sense nodes. Control circuitry is configured to perform a sensing operation on the memory cells of a selected word line of the plurality of word lines. During the sensing operation, the control circuitry determines a data state to be sensed and then sets a sense time as a function of the data state to be sensed. The control circuitry then applies a reference voltage to the selected word line and, for the sense time, discharges a selected sense node of the plurality of sense nodes through a selected NAND string of the plurality of NAND strings. The selected NAND string includes a selected memory cell of the plurality of memory cells.
