Lithium-drift based resistive processing unit for accelerating machine learning training
Resistive processing unit including: a plurality of transistors each having a lithium-doped region, wherein the plurality of transistors are arranged in an array to provide resistance; at least one first transmission line electrically connected to a source region of each transistor in at least one column of the array; at least one second transmission line electrically connected to a drain region of each transistor in at least one row of the array; and at least one third transmission line electrically connected to a gate region of the plurality of transistors in at least one row of the array; wherein application of an electrical voltage to the at least one first transmission line, the at least one second transmission line or the at least one third transmission line mobilizes lithium ions in the lithium region, thereby affecting a channel resistance of at least one transistor in the plurality of transistors.
