Modern computer technology is based on the binary logic
system.
However, the slowdown of its development calls for transition to multivalued
logic (MVL) systems. MVL can yield a denser logic implementation on
the same chip area at low cost. More information can be transmitted
with the same digits over fewer interconnections, thereby reducing
power dissipation. Here, we suggest a novel nonvolatile balanced ternary
memory based on the multiferroelectric material GeSnTe2. Two different directions and quantities of electric polarization
are found to be stable in atomic-thick two-dimensional structures.
The balanced ternary data set of {−1, 0, +1} can be implemented
in the two-dimensional material on the nanometer scale. One-shot read/write
processes are suggested.
