摘要： A small-area side-capacitor read-only memory device, a memory array and a method for operating the same are provided. The small-area side-capacitor read-only memory device embeds a field-effect transistor in a semiconductor substrate. The field-effect transistor includes a first dielectric layer and a first conductive gate stacked on the first dielectric layer. The side of the first conductive gate extends to the top of the second dielectric layer and connects to the second conductive gate to generate a capacitance effect. The second conductive gate has finger portions connected to a strip portion. Thus, the memory device employs the smallest layout area to generate the highest capacitance value, thereby decreasing the overall area of the read-only memory and performing efficient reading and writing.

摘要： The present invention discloses a low voltage difference-operated EEPROM and an operating method thereof, wherein at least one transistor structure is formed in a semiconductor substrate and each includes a first electric-conduction gate. An ion implantation is performed by masking partial regions to prevent the existence of the conventional lightly doped drain (LDD) structure. An undoped region is formed in the semiconductor substrate under the two sides of the first electric-conductive gate, to increase the intensity of electric field between the gate and the substrate or between the gate and the transistor, whereby to reduce the voltage differences required for writing and erasing. The present invention also discloses an operating method for the low voltage difference-operated EEPROM. The present invention applies to the EEPROM with a single gate transistor structure.

摘要： A low-voltage anti-fuse element is provided with a first gate dielectric layer and a first gate sequentially disposed on a substrate. A first ion-doped region is formed in the substrate on one side of the first gate. The first gate includes a body portion and a sharp corner portion extending and gradually reducing from one side of the body portion both adjacent to the first gate dielectric layer. During the operation, the principle of higher density of charges at sharp corners is utilized. When the write voltage is applied between the first gate and the first ion-doped region, a portion of the first gate dielectric layer below the sharp corner portion is liable to break down. Therefore, the breakdown voltage is reduced to achieve the purpose of reducing current consumption, while decreasing the gate area, the element size and production costs.

摘要： A small-area and low-voltage anti-fuse element comprises four first gate dielectric layers each two symmetrically distributed; and an anti-fuse gate formed on the first gate dielectric layers, wherein four corners of the anti-fuse gate respectively overlap corners of the first gate dielectric layers, which are closest to the anti-fuse gate; each of the four corners of the anti-fuse gate is fabricated to have at least one sharp angle. The present invention is characterized in that four first gate dielectric layers share an anti-fuse gate and that the sharp angle has a higher density of charges. Therefore, the present invention can greatly reduce the size of elements, lower the voltage required to puncture the first gate dielectric layer, and decrease the power consumption. The present invention also discloses a small-area and low-voltage anti-fuse array.

摘要： An operating method of an EEPROM cell is provided. The EEPROM cell comprises a transistor structure disposed on a semiconductor substrate and the transistor structure comprises a first electric-conduction gate. The-same-type ions are implanted into the semiconductor substrate between an interface of its source, drain and the first electric-conduction gate, or into the ion doped regions of the source and the drain, so as to increase ion concentrations in the implanted regions and reduce voltage difference in writing and erasing operations. The operating method of the EEPROM cell provides an operating condition that the drain or the source is set as floating during operations, to achieve the objective of rapid writing and erasing of a large number of memory cells. The proposed operating method is also applicable to the EEPROM cell having a floating gate structure in addition to a single gate transistor structure.
