Hybrid phase field effect transistor
An insulating layer is deposited over a transistor structure. The transistor structure comprises a gate electrode over a device layer on a substrate. The transistor structure comprises a first contact region and a second contact region on the device layer at opposite sides of the gate electrode. A trench is formed in the first insulating layer over the first contact region.

SELF-GATED RRAM CELL AND METHOD FOR MANUFACTURING THE SAME
The present disclosure discloses a self-gated RRAM cell and a manufacturing method thereof; which belong to the field of microelectronic technology. The self-gated RRAM cell comprises: a stacked structure containing multiple layers of conductive lower electrodes; a vertical trench formed by etching the stacked structure; a M.sub.8XY.sub.6 gated layer formed on an inner wall and a bottom of the vertical trench; a resistance transition layer formed on a surface of the M.sub.8XY.sub.6, gated layer; and a conductive upper electrode formed on a surface of the resistance transition layer, the vertical trench being filled with the conductive upper electrode. The present disclosure is implemented on a basis of using the self-gated RRAM as a memory cell. It may not depend on a gated transistor and a diode, but relies on a non-linear variation characteristic of resistance of its own varied with voltage to achieve a self-gated function, which has a simple structure, easy integration, high density and low cost, capable of suppressing a reading crosstalk phenomenon in a cross array structure; and is also adapted for a planar stacked cross array structure and a vertical cross array structure, achieving 3D storage with a high density.
RESISTIVE RANDOM ACCESS MEMORY
A resistive random access memory includes a memory cell disposed at an intersection point between a first conductive line and a second conductive line. The memory cell includes a selector structure, a first current limiter structure and a resistor structure. The first current limiter structure is disposed between the selector structure and the first conductive line. The resistor structure is disposed between the selector structure and the second conductive line or between the first current limiter structure and the first conductive line.
NONVOLATILE SCHOTTKY BARRIER MEMORY TRANSISTOR
An apparatus for high density memory with integrated logic. Specifically, a three terminal resistive random access memory (ReRAM) device having Schottky barriers that can switch from a low resistive state to a high resistive state is provided. The Schottky transistor memory device includes an insulating layer, a source region disposed on the insulating layer, a drain region disposed on the insulating layer, a binary or complex oxide memory material, a gate dielectric layer, and a gate electrode. As voltage is applied the Schottky barrier breaks down leading to the formation of a conductive anodic filament (CAF). The CAF is non-volatile and short-circuits the reverse-biased barrier thus keeping the device in a low resistance state. Removing the CAF switches the device back to a high resistance state. Thus, a new type of semiconductor device advantageously combines computation and memory further providing for very high density NAND chains.
