Memristors and Adaptation of New Technologies in Standard Process
Abstract: Silicon technology advancement has reduced its speed in the past few years. This is mainly due to the fact that minimization of silicon to smaller nodes sizes doesn’t increase the performance of the basic building block (transistor) of the microelectronic industry as it used to, due to short channel effects. Thus, an extensive research is made for new materials and technologies to keep the high improvement rate of the microelectronic industry. However, a large portion of these new devices are using new materials that are not in use in the standard microelectronic process, consequently an integration of these device in the silicon standard process is not possible.
Photonic device offer a large variety of advantages across electron devices such as better signal isolation, reliability and mostly high speeds. However these optic gates are not made of standard materials. In order to make the integration of the optic device into the standard process it is necessary to use the same materials. Additionally not much has been done for checking and adapting the new optic device to process variations caused in the standard process.
Memristor is another flavor of these new devices and is holding high promises. They were discovered by Leon Chua and recognized as the 4’th basic circuit device. Research has been done regarding the opportunity to build logic circuits with memristors and their resembles to neurons which are the basic building blocks of the brain is a very promising path for futures circuits design, but mostly their ability to function as a nonvolatile memory cell.
In this work: A new novel photonic XOR gate is introduced. This XOR gate is adapted to standard process by changing its structure and materials. Lastly, a novel photonic memory cell is introduced. Additionally, the memristor cell is researched for the opportunity to create multi-bit memory nonvolatile cell. A simulation of the device with an ADC as a prove of concept is additionally presented, with full analysis of the ADC.
