A memory device is described, including a gate over a substrate, a gate dielectric between the gate and the substrate, and two charge storage layers. The width of the gate is greater than that of the gate dielectric, so that two gaps are present at both sides of the gate dielectric and between the gate and the substrate. Each charge storage layer includes a body portion in one of the gaps, a first extension portion connected with the body portion and protruding out of the corresponding sidewall of the gate, and a second extension portion connected to the first extension portion and extending along the sidewall of the gate, wherein the edge of the first extension portion protrudes from the sidewall of the second extension portion.
