Abstract: An approach for representing both positive and negative weights in neuromorphic computing is disclosed. The approach leverages a double gate FeFET (ferroelectric field effect transistor) device. The device leverages a double-gate FeFET with four terminals (two separate gates and source and drain) and ferroelectric gate dielectric. The device may have a junction-less channel. A synaptic weight is programmed by biasing one of the two gates. The store weight is sensed via a current flow from source to drain. A pre-defined bias is applied to the other gate during the sensing, such that a reference current is subtracted from the drain current. The net current for sensing is current from the synaptic devices subtracted by the pre-defined reference current.

Abstract: A semiconductor device includes a ferroelectric random-access memory (FeRAM) cell. The FeRAM includes a ferroelectric dielectric that is annealed to attain its ferroelectric phase by an induced current flow and heating process. The current flow may be induced though a temporary wire that causes heating of the FeRAM cell. The resulting heating or anneal of the ferroelectric dielectric may crystalize the ferroelectric dielectric to embody or result in having ferroelectric properties. The induced current flow and heating process is substantially local to the FeRAM cell, and to ferroelectric dielectric therein, as opposed to a global heating or annealing process in which the entire semiconductor device, or a relatively larger region of semiconductor device, is heated to the requisite annealing temperature of ferroelectric dielectric.
