A circuit in dynamic random access memory devices includes a command extension circuit. The command extension circuit is configured to generate at least one multiple-cycle command signal by lengthening a single-cycle clock command signal from a command decoding circuit. Control logic extends and reduces the multiple-cycle command signal to provide additional functions such as burst length and burst chop. Additional control logic is configured to determine whether a clock signal is enabled in output control logic circuitry according to the multiple-cycle command and logic level generated in the output logic circuitry.

A trench extends from a main surface of a semiconductor substrate to a predetermined depth. A gate oxide layer is formed in the trench. A buried gate electrode is formed at a lower portion of the trench. The buried gate electrode is capped with a dielectric layer. A pad layer and hard mask layer are formed on the semiconductor substrate. A recess through the pad layer and hard mask layer and into the semiconductor substrate is formed on one side of the trench. A portion of the dielectric layer is revealed within the recess. The hard mask layer is then removed. An ion implantation process is performed to implant dopants on both sides of the trench, thereby forming a source doping region and a drain doping region. The source doping region has a junction depth that is deeper than that of the drain doping region.
