Abstract
A memory device includes a first state transistor and a second state transistor having a common control gate. A first selection transistor is buried in the semiconductor body and coupled to the first state transistor so that current paths of the first selection transistor and first state transistor are coupled in series. A second selection transistor is buried in the semiconductor body and coupled to the second state transistor so that current paths of the second selection transistor and second state transistor are coupled in series. The first and second selection transistors have a common buried selection gate. A dielectric region is located between the common control gate and the semiconductor body. A first bit line is coupled to the first state transistor and a second bit line is coupled to the second state transistor.
