Abstract
In an embodiment, a 3-dimensional flash memory device includes: a gate extending in a vertical direction on a semiconductor substrate; a charge storing layer surrounding the gate; a silicon layer surrounding the charge storing layer; a channel region vertically formed in the silicon layer; and source/drain regions vertically formed on both sides of the channel region in the silicon layer. Integration can be improved by storing data in a 3-dimensional manner; a 2-bit operation can be performed by providing transistors on both sides of the gate.
