Abstract
A three dimensional semiconductor device stack includes a first non-volatile memory array device, a second non-volatile memory array device, and a functional device. The first non-volatile memory array device includes a plurality of planes. The second non-volatile memory array device included a plurality of planes. The functional device is electrically connecting to the first non-volatile memory array device and the second non-volatile memory array device. The functional device includes a z-direction switch and a plane switch. The z-direction switch is configured to select one of the first non-volatile memory array device and the second non-volatile memory array device, and the plane switch is configured to select one of the planes of the selected first non-volatile memory array device or the selected second non-volatile memory array device. A method of operating the three dimensional semiconductor device stack is also disclosed.
