Abstract:
1. A non-volatile memory cell, comprising: an X line; a first Y line; a second Y line; a third Y line; a semiconductor region of a first type running along the X line; first resistance-switching material and a first semiconductor region of a second type between the first Y line and the semiconductor region of the first type, the first semiconductor region of the second type is adjacent to the semiconductor region of the first type; second resistance-switching material and a second semiconductor region of the second type between the second Y line and the semiconductor region of the first type, the second semiconductor region of the second type is adjacent to the semiconductor region of the first type; first static resistance material and a third semiconductor region of the second type between the third Y line and the semiconductor region of the first type, the third semiconductor region of the second type is adjacent to the semiconductor region of the first type; and control circuitry in communication with the X line, the first Y line, the second Y line and the third Y line; the control circuitry changes the non-volatile memory cell to a first state by causing a first current to flow from the third Y line to the first Y line through the first static resistance material and the first resistance-switching material.
