Impact of TID on the Analog Conductance and Training Accuracy of CBRAM-Based Neural Accelerator

The changes caused by total ionizing dose (TID) in the conductance of the analog response of Ag-Ge30Se70 conductive bridge random access memory (CBRAM) based synapses are studied. The conductance was seen to be severely affected by 60Co gamma ray exposure. The devices were tested up to a TID of 1 Mr...
