The volatility of Static Random Access Memory ( SRAM ) cells used in today ’ s RAM and Field Programmable Gate Array ( FPGA ) circuits consumes a significant amount of power for retention of logic information . There is great demand for non-volatile memory devices due to the need for dense and faster storage devices for the modern-day electronic applications . We are working on the development of memristorbased FPGA architecture that replaces CMOS-based components with memristor-based circuits . The memristor-based circuits that have been developed are : memristive D flip-flop , non-volatile Look-Up Table , and memristive switch block .
Propelled by investigations and discoveries in the field of semiconductors , the advent of light-emitting diodes ( LEDs ) has drastically changed the way humans approach illumination . Besides being much more energy efficient and compact , LEDs can be switched on and off at a much higher frequency . This is a key enabling factor for a modern implementation of a communication method that has roots since the time of Alexander Graham Bell and his photophone . Enter the visible light communication ( VLC ). As congested electromagnetic spectrum used by radiofrequency communication technologies like 4G , 5G , WiFi and ZigBee
Although it is estimated that current memristors are able to hold 8 times more memory than current memory devices , we investigate the possibility of developing a multilevel memristor that will store 16 times more memory .
can cause massive interference between the rapidly growing numbers of smart devices indoors , VLC is an effective complementary communication system . My research work aims to develop and integrate LED luminaires used for general lighting with VLC controllers to aid in the growth of smart Internet of Things ( IoT ) devices , while satisfying a decent baseline of quality illumination for human health .
Memristor structure : ( a high resistance , and ( b ) low resistance , where a conducting channel is formed .
