An air-fuel ratio control apparatus for an internal combustion engine, implementing integral correction of the air-fuel ratio by an integral term edfii obtained by multiplying an integrated difference between a target air fuel ratio and the actual air-fuel ratio by an integral gain, wherein the upper and lower limit values of the integral term are set based on the actual intake air amount and the actual air-fuel ratio. This limits the range of the integral term edfii to prevent it from being set at an excessively high or low level removed from the realities of the intake air amount and the air-fuel ratio, and thereby to prevent erroneous air-fuel ratio correction by the integral term.

Memory architecture with a current controller and reduced power requirements

Disclosed is a memory architecture comprising at least one memory bit cell and at least one read bit line whose voltage is controlled and changed by a current from a current controller. Each memory bit cell has a storage mechanism, a controlled current source, and a read switch. The controlled current source in each memory bit cell is electrically connected to the read bit line through the read switch. The current from the current controller that controls and changes the read bit line voltage flows through the controlled current source in the memory bit cell. The value of this current is determined by a function of a difference between the voltage on the storage mechanism in the memory bit cell and a reference voltage from a reference voltage input to the current controller. In some versions an indicator is provided for indicating when to stop the current in the controlled current source that controls a voltage change on one of the read bit lines. The indicator has an on and an off condition and a switch is provided for stopping the current in the controlled current source when the indicator is activated in the on condition. The current in the controlled current source is stopped when the voltage change on the read bit line is greater than a predetermined threshold.

Determining an Optimal Data Transfer Rate Via a Transfer Medium

Sequences that respectively comprise different data are transmitted via a transfer medium, the transfer quality being detected in accordance with the transmitted sequences. Accordingly, the sequences to be transmitted are assigned to several chronologically sequential stages, the sequences that are assigned to one stage having a pre-definable interval in terms of the data transfer rate. The following steps are executed cyclically: a) transmission of at least part of the sequences that are assigned to the first stage and selection of an interval that is situated between two transmitted sequences, in accordance with the determined transfer quality; b) transmission of at least part of the sequences that lie in the selected interval and that are assigned to the subsequent stage. Thus an optimal data transfer rate can be accurately determined for the transmission of information via the transfer medium.

Semiconductor device and method for manufacturing the same

In a semiconductor device in which a source / drain and a wiring layer are connected to each other through an associated buried conductive layer, a separation width of the buried conductive layer on a upper portion of a gate electrode is made small to manufacture a highly reliable and fine MOS transistor. After a silicon oxide film has been formed on a first polycrystalline silicon film to be aligned with a width of a gate electrode, a second polycrystalline silicon film formed on the whole surface of a substrate is selectively etched away so as to be left only on both side faces of a pattern of the silicon oxide film. Thereafter, the first polycrystalline silicon film is selectively etched away with both the silicon oxide film and the second polycrystalline silicon film as an etching mask so that the first polycrystalline film is separated with a width which is smaller than that of the gate electrode by a width of a pattern of the second polycrystalline silicon film. As a result, the buried conductive layer including the first and second polycrystalline silicon films is formed.
