发明名称 HIGH K STACK FOR NON-VOLATILE MEMORY
摘要 A memory device may include a source region and a drain region formed in a substrate and a channel region formed in the substrate between the source and drain regions. The memory device may further include a first oxide layer formed over the channel region, the first oxide layer having a first dielectric constant, and a charge storage layer formed upon the first oxide layer. The memory device may further include a second oxide layer formed upon the charge storage layer, a layer of dielectric material formed upon the second oxide layer, the dielectric material having a second dielectric constant that is greater than the first dielectric constant, and a gate electrode formed upon the layer of dielectric material.
