    摘要: A non-volatile memory device includes a semiconductor layer including source and drain regions and a channel region between the source and drain regions; a tunneling insulating layer on the channel region of the semiconductor layer; a charge storage layer on the tunneling insulating layer; a blocking insulating layer on the charge storage layer and including a first oxide layer with a first thickness, a high-k dielectric layer, and a second oxide layer with a second thickness different from the first thickness that are stacked sequentially on the charge storage layer; and a control gate on the blocking insulating layer.
