    摘要: The present invention aims at providing a semiconductor memory device that can be manufactured by a MOS process and can realize a stable operation. A storage transistor has impurity diffusion regions, a channel formation region, a charge accumulation node, a gate oxide film, and a gate electrode. The gate electrode is connected to a gate line and the impurity diffusion region is connected to a source line. The storage transistor creates a state where holes are accumulated in the charge accumulation node and a state where the holes are not accumulated in the charge accumulation node to thereby store data “1” and data “0”, respectively. An access transistor has impurity diffusion regions, a channel formation region, a gate oxide film, and a gate electrode. The impurity diffusion region is connected to a bit line.

    摘要: In this semiconductor memory device, a potential clamping region having no insulation layer formed therein is provided in an insulation layer. More specifically, the potential clamping region is formed under a body portion at a position near a first impurity region, and extends to a first semiconductor layer. A body fixing portion is formed in a boundary region between the body portion and the potential clamping region. This structure enables improvement in operation performance without increasing the layout area in the case where a DRAM cell is formed in a SOI (Silicon On Insulator) structure.

    摘要: A voltage down converter includes a first voltage down converting circuit and a second voltage down converting circuit. The first voltage down converting circuit supplies an internal power supply voltage VCCS1 to an internal circuit only during a period T when the internal power supply voltage VCCS1 falls below a predetermined voltage according to a signal DCE. In the first voltage down converting circuit, P channel MOS transistors are selectively activated according to the levels of the plurality of voltages, and a voltage down converting partial circuit supplies a current of an amount corresponding to the level of the external power supply voltage VCC to a power supply node. As a result, even during the period T, the internal power supply voltage can be maintained at a level of the reference voltage.
