Abstract:
1. A random access memory cell comprising: a first n-type region comprising germanium in contact with a first p-type region comprising germanium and forming a first pn junction therebetween; a second n-type region comprising germanium in contact with a second p-type region comprising germanium and forming a second pn junction therebetween; a first gate electrode overlying a portion of the first n-type region; a second gate electrode overlying a portion of the first p-type region; a third gate electrode overlying a portion of the second n-type region; a fourth gate electrode overlying a portion of the second p-type region; a first interconnect coupled to the first n-type region, the second gate electrode, and a first terminal configured for coupling to a first voltage reference; a second interconnect coupled to the first p-type region, the first gate electrode, the second n-type region, and the fourth gate electrode; a third interconnect coupled to the second p-type region, the third gate electrode, and second terminal configured for coupling to a second voltage reference; and a pass device coupled to a bit line, a word line and to the second interconnect.
