    摘要： A control circuit for a vehicle-mounted air conditioner having plural dampers therein comprises a manual command entry unit for entering command signals to a computer unit. The computer unit includes a first computer constantly powered by a vehicle-mounted storage battery to receive a temperature resetting command signal from the entry unit and a second computer which is powered from the battery through an engine ignition key switch to receive control data from the first computer to control the air conditioner. A plurality of operating parameter sensors also supplies sensed operating parameters to the second computer to permit it to control one or more of the dampers to direct conditioned air to the vehicle compartment. A display unit receives data from the computer unit to provide visual display of the reference temperature and the operating conditions of the air conditioner.

    摘要： This invention provides an interface circuit for detecting that a DQS signal from a DDR SDRAM is at an intermediate potential. An interface circuit is connected to at least a signal line which transmits the DQS signal from the DDR SDRAM and reaches an intermediate potential VM when the signal attains an inactive state. The interface circuit has a comparing portion for comparing the potential of the DQS with a threshold potential VREFH which is a potential that is different from the intermediate potential VM.

    摘要： Plural transmitter units generate plural currents corresponding to plural logical values, respectively, and propagate the currents to a common signal line. The common signal line synthesizes the currents generated by the transmitter units, and propagates them to a receiver unit as a synthetic current. The receiver unit restores the logical values the transmitter units generated, in accordance with the synthetic current. The values of the currents the transmitter units generate in correspondence with the logical values each differ, so that the value of the synthetic current can be changed for every combination of logical values. Accordingly, the receiver unit can restore the logical values outputted from the respective transmitter units, based on the synthetic current. That is, employing the common signal line enables signals transmitted from the transmitter units to be simultaneously received. Consequently, the number of signal lines laid between the transmitter units and the receiver unit is reduced.

    摘要： It is intended to provide a semiconductor integrated circuit device permitting reading of information specific to chips within the mounted chips while restraining the increase in the total number of terminals of the package and enabling the area of circuits required for reading information specific to chips to be made smaller than that according to the prior art, and a control method therefor. The same terminal is used as the external terminal to which the pulse signals are inputted and the external terminal from which the chip-specific information is outputted. Also, the external terminal for inputting/outputting required power supply in the normal operation mode and the external terminal for reading chip-specific information in the information reading mode are used in common. The increase in the number of external terminals can be thereby restrained. Moreover, the counter unit is shared between functional circuits and the comparative decision unit. This can serve to restrain the increase in chip area.

    摘要： A memory device for ensuring efficient access and reduction in current consumption. The memory device includes a plurality of memory cells arranged in accordance with a first address and a second address which define a logical address map indicating a logical shape of the memory array. An address map changing unit is operatively coupled to the memory array, for receiving a first address signal for generating the first address and a second address signal for generating the second address. The address map changing unit is capable of changing the logical address map by altering a part of one of the first address signal and the second address signal.

    摘要： It is intended to provide a memory control device and memory control method capable of reducing charge/discharge current consumed while various commands are inputted to a semiconductor memory device and reducing occurrence of power noises. During periods TT1, TT2, and TT3 which are parts of a period tCKE in which a clock enable signal CKE is in active state, supply of a control clock SD_CLK from a memory control device 1 to a synchronous-type semiconductor memory device 12 can be stopped. Furthermore, in case an input of a data input/output period of an external command and that of refresh operation period of a refresh command RCMD overlap and an access region of the external command and that of the refresh command RCMD do not coincide, those commands are converted to control command signal SD_CMD in parallel, whereby parallel conversion processing operation can be conducted.

The power supply circuit includes a first power supply circuit, which generates a step down voltage by decreasing a first voltage on the external power supply in a normal operation mode, a second power supply circuit, which supplies the internal circuit with a second voltage on the external power supply in a self-refresh mode, and a detection circuit, which detects entry to the self-refresh mode and a voltage level of the external power supply and generates a detection signal based on the detection. During the self-refresh mode, the first power supply circuit receives the second voltage from the external power supply, and the first and second power supply circuits supply the internal circuit with the second voltage based on the detection signal.
