    摘要: A non-volatile memory is described. The non-volatile memory includes a first source/drain region, a second source/drain region, a charge-trapping layer and a gate layer. The first source/drain region is disposed beside the top sidewall of a trench in a substrate. The second source/drain region is disposed in the substrate at the bottom of the trench. The gate layer is disposed in the trench and on the substrate. The charge-trapping layer is disposed between the gate layer and the substrate. A plurality of assisted charges is stored in one of the sides of the charge-trapping layer.
