A Comprehensive Study on the Characteristics, Complex Materials and Applications of Memristor

In 1971, Leon Chua postulated the fourth passive element memristor [1], which establishes a nexus between charge and flux. The memory property of the proposed memristor portrays the fact that its memristance is obtained by the past history of driving input. If the driving input is detached, the ideal memristor device will maintain its current state until the device was driven by new input. By using this property, the existing Complementary Metal Oxide Semiconductor (CMOS) based memory block can be replaced by memristor based memory block for potentially higher density, low energy and low power consumption. This review paper throws research highlights on the characteristics, complex materials used for fabrication, various applications and approaches of memristor.
