摘要： A semiconductor integrated circuit includes a temperature detecting unit that detects the temperature of a chip, and an A/D converter that converts an analog output VBE from the temperature detecting unit into a digital output. The A/D converter includes an up/down counter, a D/A converter that converts an output T2 from the up/down counter into an analog output, and a comparator that compares the analog output DAC_OUT of the D/A converter and the analog output VBE (VTEMP) of the temperature detecting unit. The up/down counter is adapted to be able to preset an initial value that is different from the minimum value or the maximum value. Accordingly, the determination time required at the initial conversion can be reduced although the linear search method is used.

摘要： An electrically programmable and erasable non-volatile semiconductor memory such as a flash memory is designed into a configuration in which, when a cutoff of the power supply occurs in the course of a write or erase operation carried out on a memory cell employed in the non-volatile semiconductor memory, the operation currently being executed is discontinued and a write-back operation is carried out to change a threshold voltage of the memory cell in the reversed direction. In addition, the configuration also allows the number of charge-pump stages in an internal power-supply configuration to be changed in accordance with the level of a power-supply voltage so as to make the write-back operation correctly executable. As a result, no memory cells are put in deplete state even in the event of a power-supply cutoff in the course of a write or erase operation.

摘要： A semiconductor device in which the insulation characteristics of an insulating film of multilayer structure including a lower-layer insulating film and a high-dielectric-constant film formed on the lower-layer insulating film are ensured, and a method for fabricating such a semiconductor device. A silicon oxide film or a silicon oxynitride film is formed on a semiconductor substrate as a lower-layer insulating film and part of the lower-layer insulating film is removed. Then a high-dielectric-constant film the dielectric constant of which is higher than that of the lower-layer insulating film is formed on the exposed semiconductor substrate and the lower-layer insulating film. If the lower-layer insulating film is a silicon oxide film, then a metallic compound not including chlorine is used for forming this high-dielectric-constant film. If the lower-layer insulating film is a silicon oxynitride film, then a metallic chloride can be used for forming this high-dielectric-constant film.

摘要： A semiconductor IC device is designed using a memory core with a plurality of I/O lines, a transfer circuit module and a logic library which are produced beforehand and stored in a data base. The memory core and a logic circuit are arranged so that their I/O lines extend in the same direction. A transfer circuit including plural stages of switch groups is arranged between the I/O lines of the memory core and the I/O lines of the logic circuit. Switches forming each stage of switch group are formed between the I/O lines of the memory core and the I/O lines of the logic circuit. When one stage of or a small number of stages of switch groups are turned on, the I/O lines of the memory core and the I/O lines of the logic circuit are turned on, thereby forming a desired transfer pattern. The memory core is constructed by the combination of functional modules such as an amplifier module, a bank module and a power supply module. In the bank module are arranged row-system circuits which operate independently of each other and a multiplicity of I/O lines which extend in a bit line direction.
