Abstract

NOR flash memory that includes three-dimensional memory cells is provided. In the NOR flash memory of the present disclosure, one memory cell includes one memory transistor and one selection transistor. A common sourceis formed over a silicon substrate, and an active regionextending in a vertical direction to electrically connect to the common sourceis formed. A control gateof the memory transistor and a selection gate lineof the selection transistor are formed to surround a side portion of the active region, and a top portion of the active regionis electrically connected to a bit line
