    摘要: In one embodiment, a method of fabricating one or more transistors in an integrated circuit includes an annealing step prior to a gate oxidation step. The annealing step may comprise a rapid thermal annealing (RTA) step performed prior to a gate oxidation pre-clean step. Among other advantages, the annealing step reduces a step height difference between P-doped and N-doped regions of a field oxide of a shallow trench isolation structure. The shallow trench isolation structure may be separating a PMOS transistor and an NMOS transistor in the integrated circuit.

    摘要: Apparatus and method for providing overcurrent protection to a resistive random access memory (RRAM) cell during an RRAM formation process used to prepare the cell for normal read and write operations. In accordance with various embodiments, the RRAM cell is connected between a first control line and a second control line, and an active protection device (APD) is connected between the second control line and an electrical ground terminal. A formation current is applied through the RRAM cell, and an activation voltage is concurrently applied to the APD to maintain a maximum magnitude of the formation current below a predetermined threshold level.

    摘要: A resistive sense memory apparatus includes a bipolar select device having a semiconductor substrate and a plurality of transistors disposed in the semiconductor substrate and forming a row or transistors. Each transistor includes an emitter contact and a collector contact. Each collector contact is electrically isolated from each other and each emitter contact is electrically isolated from each other. A gate contact extends along a channel region between the emitter contact and a collector contact. A base contact is disposed within the semiconductor substrate such that the emitter contact and a collector contact is between the gate contact and the base contact. A resistive sense memory cells is electrically coupled to each collector contact or emitter contact and a bit line.
