摘要:
The well voltage of a CMOS circuit having low-threshold-voltage MOSFETs is controlled when the power supply is turned on, during normal operation, and when the supply voltage is cut off. The CMOS circuit can thus operate stably with lower power consumption, because latching-up is reduced when the supply voltage is applied to the CMOS circuit or when the supply voltage is cut off, and subthreshold current is decreased during normal operation.

An electronic processor is provided for use with a memory (2530) having selectable memory areas. The processor includes a memory area selection circuit (MMU) operable to select one of the selectable memory areas at a time, and an instruction fetch circuit (2520, 2550) operable to fetch a target instruction at an address from the selected one of the selectable memory areas. The processor includes an execution circuit (Pipeline) coupled to execute instructions from the instruction fetch circuit (2520, 2550) and operable to execute a first instruction for changing the selection by the memory area selection circuit (MMU) from a first one of the selectable memory areas to a second one of the selectable memory areas, the execution circuit (Pipeline) further operable to execute a branch instruction that points to a target instruction, access to the target instruction depending on actual change of selection to the second one of the memory areas; and the processor includes a logic circuit (3108, 3120, 3125, 3130, 3140) operable to ensure fetch of the target instruction in response to the branch instruction after actual change of selection. Other circuits, devices, systems, apparatus, and processes are also disclosed.

A microfabrication apparatus for pressing an original plate including a pattern down on a substrate to transfer the pattern on the substrate includes a first measurement unit for measuring relative positional displacement between the substrate and the plate above the substrate, a position correction unit for correcting relative position between the substrate and the plate such that the pattern is to be transferred on a first predetermined position of the substrate based on the relative positional displacement measured by the first measurement unit, a pressing unit for pressing the plate above the substrate down on the substrate to transfer the pattern on the substrate in a state that the relative positional displacement between the substrate and the plate is corrected by the position correction unit, and a second measurement unit for measuring relative positional relationship between the pattern transferred on the substrate and a pattern previously formed on the substrate.

A low power consumption in a semiconductor integrated circuit device can be achieved by reducing a glitch power in a flip-flop. In a pulse-generator-incorporated auto-clock-gating flip-flop in which data latch is performed by using a pulsed clock, input data is latched based on an output of a dynamic XOR circuit, which is a comparator circuit, during a period when the pulsed clock is at a high level, and the dynamic XOR circuit is cut off during a period when the pulsed clock is at a low level.

摘要:
In a low power consumption mode in which prior data is retained upon power shutdown, the return speed thereof is increased. While use of an existent data retaining flip-flop may be considered, this is not preferred since it increases area overhead such as enlargement of the size of a cell. A power line for data retention for power shutdown is formed with wirings finer than a usual main power line. Preferably, power lines for a data retention circuit are considered as signal lines and wired by automatic placing and mounting. For this purpose, terminals for the power line for data retention are previously designed by providing the terminals therefor for the cell in the same manner as in the existent signal lines. Additional layout for power lines is no longer necessary for the cell, which enables a decrease in the area and design by an existent placing and routing tool.

A semiconductor device having a functional circuit block with predictive power controller is provided so as to construct a system LSI manufactured in a practicable number of design steps, which is extensible and in which power is reduced. The functional circuit block includes a prediction circuit and a predictive power shutdown circuit having a power status control circuit. The prediction circuit controls a power status of the functional circuit block by using the power status control circuit, based on input information thereto. When no information is inputted for a predetermined a period of time, the power status control circuit shifts from a power status of the functional circuit block to a low-power status.
摘要:
A preventive and/or therapeutic agent for inflammatory respiratory tract diseases containing, as an active ingredient, a steroid derivative represented by the following formula (1): (wherein R represents a hydrogen atom, a halogen atom, a hydroxy group, or —OCOR1 (wherein R1 represents a linear or branched alkyl group which may be substituted by a halogen atom or a cycloalkyl group; a cycloalkyl group; or an aryl group)). These compounds can continuously suppress respiratory tract inflammation and respiratory tract hyperreaction and show a high site selectivity and little systemic effect when administered directly to the respiratory tract. By virtue of these characteristics, these compounds are remarkably useful in clinical medicine as highly safe preventive and/or therapeutic agents for inflammatory respiratory tract diseases which can be administered for a long period of time.
