A semiconductor memory element is described, including a substrate including a source region, a drain region, and a channel region, a tunnel oxide over the channel region of the substrate, a charge storage layer over the tunnel oxide, a charge blocking layer over the charge storage layer, and a control gate over the charge blocking layer. The charge blocking layer further includes a first layer including a transition metal oxide, a second layer including a metal silicate, a third layer including the transition metal oxide of the first layer. |
