Abstract
A method for operating a three-dimensional (3D) memory device includes performing a first read operation for sensing a first memory cell of a first transistor string, and performing a subsequent second read operation for sensing a second memory cell of a second transistor string. Performing the first read operation includes applying a first bit line voltage to a first bit line, and maintaining the first bit line basically undischarged after data state of the first memory cell is detected.
