    摘要: In a semiconductor memory device, a capacitor with a trench having a laterally expanded bottom part is provided, the area above the laterally expanded part being provided for a transistor and cell separation, this resulting in an increase in the degree of integration. This laterally expanded part is formed by etching a silicon oxide film which is sandwiched between a substrate and a silicon layer, and is obtained by forming a depression in a semiconductor substrate beforehand. A silicon layer or another semiconductor substrate is laminated by bonding to a semiconductor substrate such as this into which is formed a depression, a trench which extends to this depression being formed, and the required films being formed to obtain the desired trench capacitor. By forming an oxide film on all of or the depression part of the semiconductor substrate into which is formed the depression, it is possible to eliminate the influence of radiation, by improving insulation properties.

    摘要: A data processing apparatus includes an address bus, a scramble unit, and a data bus. The address bus outputs address data to be given to a memory apparatus. The scramble unit scrambles write-in data into a storage position in the memory apparatus identified by the address data to obtain confidential data. The data bus outputs the confidential data. The scramble unit includes a first scrambler, a first converter and a second scrambler. The first scrambler XORs first mask data corresponding to the address data and the write-in data for each bit and makes it first scrambled data. The first converter performs one-to-one substitution conversion of the first scrambled data. The second scrambler XORs second mask data corresponding to the address data and data after the conversion of the first scrambled data by the first converter and outputs obtained second scrambled data as the confidential data.

    摘要: A fuel cell system is capable of easily determining whether or not supply of gas to a cathode has been cut off after an issuance of a power generation stop command. The fuel cell system includes a cell stack which includes a plurality of fuel cells; a stop valve which is brought to a closed state as the power generation stop command is issued, thereby cutting off an inflow of air into a pipe, and therefore into the cell stack; a power generation sensor which detects a voltage of the cell stack after the issuance of the power generation stop command; and a CPU which controls an operation of the fuel cell system. When a main switch is turned off while the cell stack is in a power generating operation, an operation stop command and the power generation stop command are given to the CPU. After the power generation stop command is issued, the CPU determines whether or not air supply to the cell stack has been cut off, by comparing the voltage of the cell stack to a first threshold value.
