Hybrid nanocrystal FinFET with large P/E window for MLC NAND Flash memory application
The engineered trap layer with nanocrystal and high-k blocking oxide are applied to the FinFET structure. The increased trap density of the hybrid nanocrystal trap layer and the enhanced leakage reduction of AlxOy are proposed as a dominant role of the larger program and erase window of 8.3 V which is applicable to the MLC Flash memory device.
