    摘要: An embodiment of the invention is a transistor formed in part by a ferromagnetic semiconductor with a sufficiently high ferromagnetic transition temperature to coherently amplify spin polarization of a current. For example, an injected non-polarized control current creates ferromagnetic conditions within the transistor base, enabling a small spin-polarized signal current to generate spontaneous magnetization of a larger output current.

    摘要: An embodiment of the invention includes an analog associative memory, which includes an array of coupled voltage or current controlled oscillators, that matches patterns based on shifting frequencies away from a center frequency of the oscillators. The test and memorized patterns are programmed into the oscillators by varying the voltage or current that controls the oscillators. Matching patterns result in smaller shifts of frequencies and enable synchronization of oscillators. Non-matching patterns result in larger shifts and preclude synchronization of oscillators. In one embodiment the patterns each include binary data and the pattern matching is based on discrete shifts. In one embodiment the patterns each include grayscale data and the pattern matching is based on continuously-varied shifts. Other embodiments are described herein.
