CBRAM switch cells on copper cladded FR-4 substrates used for DC characterization studies. (a) Photograph of fabricated CBRAM switch cell matrix. (b) Layer structure of a single cell of this group. DC performance tests over 60 different cells. (c) Stability results after programming virgin cells and (d) time to target for the tested target resistances, Rt = {5 Ω, 50 Ω, 500 Ω, 5000 Ω}.
