Abstract

A memory device includes a plurality of memory cells, each of which includes a first transistor, a second transistor, and a resistor operatively coupled to each other in series. Each of the first and second transistors include a sub-transistor, the sub-transistor having a channel structure, a source structure disposed on one side of the channel structure, and a drain structure disposed on the other side of the channel structure. The resistor includes a metal structure disposed above the first and second transistors. The channel structures, source structures, and drain structures of the sub-transistors are all formed in a first active region of a substrate.
