摘要: A non-volatile memory device and a method of fabricating the same are provided. The method can include disposing an isolation layer on a semiconductor substrate. The isolation layer may protrude from the main surface of the semiconductor substrate and define an active region. In a recess defined by the protrusion of the isolation layer and the active region, a diffusion-retarding poly pattern and a floating gate may be formed in sequence. A control gate may be disposed on the isolation layer to cover the diffusion-retarding poly pattern and the floating gate.
