Memristive
devices are able to store and process information, which
offers several key advantages over the transistor-based architectures.
However, most of the two-terminal memristive devices have fixed functions
once made and cannot be reconfigured for other situations. Here, we
propose and demonstrate a memristive device “memlogic” (memory logic) as a nonvolatile switch of logic operations
integrated with memory function in a single light-gated memristor.
Based on nonvolatile light-modulated memristive switching behavior,
a single memlogic cell is able to achieve optical and electrical mixed
basic Boolean logic of reconfigurable “AND”, “OR”,
and “NOT” operations. Furthermore, the single memlogic
cell is also capable of functioning as an optical adder and digital-to-analog
converter. All the memlogic outputs are memristive for in
situ data storage due to the nonvolatile resistive switching
and persistent photoconductivity effects. Thus, as a memdevice, the
memlogic has potential for not only simplifying the programmable logic
circuits but also building memristive multifunctional optoelectronics.
