  • Patent number: 12230344
    Abstract: Technology is disclosed for testing a 3D memory structure. The 3D memory structure has blocks with layers of word lines. Each word line is connected to control gates of NAND memory cells. The 3D memory structure may be tested while concurrently applying a set of layer dependent voltages to a corresponding set of word lines. The magnitude of each layer dependent voltage may depend on which layer the word line to which the voltage is applied resides. There may be physical differences between the different layers such as differences in the diameters of the memory holes in which NAND string are formed. The layer dependent voltages provide for a more accurate test in view of these and other physical differences between the different layers.
