Abstract:
Techniques and circuitry are disclosed for efficiently implementing programmable memory array circuit architectures, including both non-volatile and volatile memories. The memory circuitry employs an antifuse scheme that includes an array of  1 T bitcells, wherein each bitcell effectively contains one gate or transistor-like device that provides both an antifuse element and a selector device for that bitcell. In particular, the bitcell device has asymmetric trench-based source/drain contacts such that one contact forms a capacitor in conjunction with the spacer and gate metal, and the other contact forms a diode in conjunction with a doped diffusion area and the gate metal. The capacitor serves as the antifuse element of the bitcell, and can be programmed by breaking down the spacer. The diode effectively provides a Schottky junction that serves as a selector device which can eliminate program and read disturbs from bitcells sharing the same bitline/wordline.

Claim (Index 16):
An integrated circuit comprising:\n a body including semiconductor material; a first spacer and a second spacer, the first and second spacers including one or more dielectrics, at least one of the first or second spacers above the body; a gate structure including one or more metals, the gate structure between the first and second spacers, the gate structure above at least a portion of the body; a first contact structure including one or more metals, the first contact structure adjacent to the first spacer, the first contact structure isolated from the body by insulator material; and a second contact structure including one or more metals, the second contact structure adjacent to the second spacer, the second contact structure in direct contact with semiconductor material.
