Bi₂O₂Se-Based Memristor-Aided Logic

Abstract

The implementation of two-dimensional materials into memristor architectures has recently been a new research focus by taking advantage of their atomic thickness, unique lattice, and physical and electronic properties. Among the van der Waals family, Bi 2 O 2 Se is an emerging ternary two-dimensional layered material with ambient stability, suitable band structure, and high conductivity that exhibits high potential for use in electronic applications. In this work, we propose and experimentally demonstrate a Bi 2 O 2 Se-based memristor-aided logic. By carefully tuning the electric field polarity of Bi 2 O 2 Se through a Pd contact, a reconfigurable NAND gate with zero static power consumption is realized. To provide more knowledge on NAND operation, a kinetic Monte Carlo simulation is carried out. Because the NAND gate is a universal logic gate, cascading additional NAND gates can exhibit versatile logic functions. Therefore, the proposed Bi 2 O 2 Se-based MAGIC can be a promising building block for developing next-generation in-memory logic computers with multiple functions.

“…Another unique property of memristive memory is its ability to perform logic operations within the crossbar [9,28,33,44,45,50,52,87], i.e., PIM. The inputs for the logic operations are memory cell-stored values and the result appears as the stored value of the output cell.…”

“…An example of a stateful logic technique is MAGIC NOR [33,37,44,50]. Since NOR is functionally complete, any logical function can be performed using a series of NOR operations (requiring additional devices for the intermediate values).…”
