    • 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.
    • 本发明的实施例包括模拟相关存储器,其包括耦合电压或电流控制振荡器的阵列,其匹配基于偏离振荡器的中心频率的移位频率的模式。 通过改变控制振荡器的电压或电流将测试和存储的模式编程到振荡器中。 匹配模式导致频率偏移较小,并使振荡器能够同步。 非匹配模式导致更大的偏移,并排除振荡器的同步。 在一个实施例中,图案各自包括二进制数据,并且模式匹配基于离散移位。 在一个实施例中,模式各自包括灰度数据,并且模式匹配基于连续变化的移位。 本文描述了其它实施例。
