摘要： A bi-directional DC-DC converter uses a transformer for both step-down and step-up operations. A switching frequency for operating a switching device is set separately for the step-down and step-up operations. When, for example, the switching frequency during the step-up operation is lower than the switching frequency during the step-down operation, the range in which the duty ratio in PWM control can be controlled is widened, compensating for step-up ratio insufficiency. Conversely, step-down ratio insufficiency is compensated for by making the switching frequency during the step-down operation lower than the switching frequency during the step-up operation.

摘要： The inventive bi-directional DC-DC converter addresses a problem of an insufficient step-up ratio during the step-up operation that is caused when a turns ratio of the transformer is determined to, for example, match the step-up operation and also address a contrary problem of an insufficient step-down ratio during the step-down operation that is caused when a turns ratio is determined to match the step-up operation. In the inventive bi-directional DC-DC converter that uses a transformer for both step-down and step-up operations, a switching frequency for operating a switching device is set separately for the step-down and step-up operations. For example, when the switching frequency during the step-up operation is lower than the switching frequency during the step-down operation, the range in which the duty ratio in PWM control can be controlled is widened, compensating for step-up ratio insufficiency. Conversely, step-down ratio insufficiency is compensated for by making the switching frequency during the step-down operation lower than the switching frequency during the step-up operation.

摘要： Herein disclosed is a semiconductor integrated circuit device comprising a SRAM having its memory cell composed of transfer MISFETs to be controlled through word lines and drive MISFETs. The gate electrodes of the drive MISFETs and the gate electrodes of the transfer MISFETs of the memory cell, and the word lines are individually formed of different conductive layers. The drive MISFETs and the transfer MISFETs are individually arranged to cross each other in the gate length direction. The word lines are extended in the gate length direction of the gate electrodes of the drive MISFETs and caused to cross the gate electrodes of the drive MISFETs partially. The two transfer MISFETs of the memory cell have their individual gate electrodes connected with two respective word lines spaced from each other and extended in an identical direction. The region defined by the two word lines is arranged therein with the two drive MISFETs and the source lines.The source line is formed of a conductive layer identical to that of the word line. The individual data lines of the complementary data line are formed of an identical conductive layer which is different from that of the word line and the source line. The identical conductive layer between the word line and source line and the complementary data line is formed with two word lines: a main word line extended in the first direction identical to that of the word line and source line and used by adopting the divided word line system: and a sub-word line used by adopting the double word line system.

摘要： Herein disclosed is a semiconductor integrated circuit device comprising an SRAM having its memory cell composed of transfer MISFETs to be controlled through word lines and drive MISFETs, and a method of forming this device. The gate electrodes of the drive MISFETs and of the transfer MISFETs of the memory cell, and the word lines, are individually formed of different conductive layers. The two transfer MISFETs of the memory cell have their individual gate electrodes connected with two respective word lines spaced from each other and extended in an identical direction. The source line is formed of a conductive layer identical to that of the word line. An oxidation resisting film is formed on the gate electrodes of the drive MISFETs so as to reduce stress caused by oxidization of edge portions of these gate electrodes, and to reduce a resulting leakage current. A thickness of an oxide film formed on gate electrodes of the transfer MISFETs and word lines is thicker than an oxide film formed on gate electrodes of the drive MISFETs, so that data line pads can be formed in self-alignment with the oxide film and side wall spacers on the gate electrodes of the transfer MISFETs.
