    Abstract: A fabricating method of a DRAM structure includes providing a substrate comprising a memory array region and a peripheral region. A buried gate transistor is disposed within the memory array region, and a planar gate transistor is disposed within the peripheral region. Furthermore, an interlayer dielectric layer covers the memory array region, the buried gate transistor and the planar gate transistor. Then, a capping layer of the planar gate transistor and part of the interlayer dielectric layer are removed simultaneously so that a first contact hole, a second contact hole and a third contact hole are formed in the interlayer dielectric layer. A drain doping region of the buried gate transistor is exposed through the first contact hole, a doping region of the planar gate transistor is exposed through the second contact hole, and a gate electrode of the planar gate transistor is exposed through the third contact hole.

    Abstract: A device for preventing current-leakage is located between a transistor and a capacitor of a memory cell. The two terminals of the device for preventing current-leakage are respectively connected with a slave terminal of the transistor and an electric pole of the capacitor. The device for preventing current-leakage has at least two p-n junctions. The device for preventing current-leakage is a lateral silicon controlled rectifier, a diode for alternating current, or a silicon controlled rectifier. By utilizing the driving characteristic of the device for preventing current-leakage, electric charge stored in the capacitor hardly passes through the device for preventing current-leakage when the transistor is turned off to improve the current-leakage problem.

    Abstract: The memory cell of the present invention has two independent storage regions embedded into two opposite sidewalls of the control gate respectively. In this way, the data storage can be more reliable. Other features of the present invention are that the thickness of the dielectric layers is different, and the two independent storage regions are formed on opposite bottom sides of the opening by the etching process and form a shape like a spacer. The advantage of the aforementioned method is that the fabricating process is simplified and the difficulty of self-alignment is reduced.

    Abstract: A flash memory is provided. The flash memory features of having the select gate transistors to include two different channel structures, which are a recessed channel structure and a horizontal channel. Because of the design of the recessed channel structure, the space between the gate conductor lines, which are for interconnecting the select gates of the select gate transistors arranged on the same column, can be shortened. Therefore, the integration of the flash memory can be increased; and the process window of the STI process can be increased as well. In addition, at least one depletion-mode select gate transistor is at one side of the memory cell string. The select gate transistor of the depletion-mode is always turned on.
