US Patent 12125531 Resistive memory device for matrix-vector multiplications

A device for performing a matrix-vector multiplication of a matrix with a vector. The device comprising a memory crossbar array comprising a plurality of row lines, a plurality of column lines and a plurality of junctions arranged between the plurality of row lines and the plurality of column lines. Each junction comprises a programmable resistive element and an access element for accessing the programmable resistive element. The memory crossbar array further comprises one or more write-assist wires and one or more corresponding arrays of switching elements. The write-assist wires are connectable via the switching elements to the plurality of column lines.
