Abstract
A memory device and a semiconductor die are provided. The memory device includes: a non-volatile storage device, with a first terminal coupled to a bit line; and an access transistor, configured to control electrical connection between a second terminal of the non-volatile storage device and a source line, and comprising an N-type field effect transistor (NFET) and a P-type field effect transistor (PFET) stacked on the NFET. A common source/drain terminal of the NFET and the PFET is coupled to the second terminal of the non-volatile storage device. Another common source/drain terminal of the NFET and the PFET is coupled to the source line. Further, gate terminals of the NFET and the PFET are coupled to different word lines.
