Memristor has two terminals structure, which allows the device to be fabricated into large crossbar array. Moreover, a single memristor has an analog switching behavior unlike conventional devices such as CMOS based processor. Due to these characteristics, effective matrix operation is possible through memristor array, which makes the memristor adequate as a device for deep learning process and artificial intelligence. The inherent memory effect of memristor removes bottlenecks between memory and processor unit, existing on conventional AI processor. Other properties such as high scalability, low power consumption and fast switching speed are the remarkable strength of memristor for AI and deep learning applications.<\/p>\n<p><img decoding=\"async\" alt=\"\" class=\"media-element file-default\" data-delta=\"1\" data-fid=\"6800\" data-media-element=\"1\" src=\"http:\/\/ee.presscat.kr\/sites\/default\/files\/%EC%B5%9C%EC%8B%A0%ED%98%841.png\" title=\"\"><\/p>\n<p><strong>\u25cf<\/strong><strong> Research area of Emerging Nano Technology and Integrated Systems Lab (ENTIS)<\/strong><\/p>\n<p>Our lab focuses are 1) to overcome the limitations of conventional memristor and 2) to develop memristor-based platform for various deep neural network(DNN), spiking neural network(SNN) and other applications.<\/p>\n<p>1. <strong>Memristor Devices Development<\/strong><\/p>\n<p>Conventional memristors suffer from unavoidable spatial-temporal variation due to uncontrollable, stochastic filament formation.
