Patent attributes
A driving method of a nonvolatile memory device including multiple memory planes includes following operations: precharging at least one word line and at least one bit line of a first memory plane; if the at least one word line and the at least one bit line of the first memory plane have been precharged for a first time length or to respective voltage thresholds, precharging at least one word line and at least one bit line of a second memory plane; conducting a first data operation to at least one memory cell of the first memory plane disposed at intersections of the at least one word line and the at least one bit line thereof; conducting a second data operation to at least one memory cell of the second memory plane disposed at intersections of the at least one word line and the at least one bit line thereof.
