    摘要: A method of forming a magnetoelectronic device includes forming a dielectric material (114) surrounding a magnetic bit (112), etching the dielectric material (114) to define an opening (122) over the magnetic bit (112) without exposing the magnetic bit (112), the opening (122) having a sidewall, depositing a blanket layer (132) of cladding material over the dielectric material (118), including over the sidewall, removing by a sputtering process the blanket layer (132) in the bottom of the opening (122) and the dielectric material (124) over the magnetic bit (112), and forming a conductive material (146) within the opening (122) to form a bit line (154). This process reduces errors caused by process irregularities such as edges of the bits (112) protruding and thereby causing defects in the cladding layer (132) formed thereover. A bit line or digit line so formed may optionally be tapered at the ends (182, 184) to prevent magnetic reversal of the bit line magnetic moment that otherwise may occur due to external magnetic fields.

    摘要: Apparatus and methods are provided for oscillators having adjustable gain. An exemplary oscillator module comprises a first node for a first voltage, a control node for a control signal, and oscillator circuitry coupled to the first node and the control node. The oscillator circuitry generates an output signal with a first oscillation frequency based on the first voltage, and in response to the control signal being asserted, the oscillator circuitry generates the output signal with a second oscillation frequency based on the first voltage. The second oscillation frequency is greater than the first oscillation frequency.
