A navigation apparatus for guiding a moving body from a current location to a destination using a communication base station includes a current location detection device for detecting a current location of the moving body and outputting current location information; a sending device for sending the current location information and destination information to the communication base station; a receiving device for receiving guiding information, which is required to guide the moving body from the current location to the destination and includes information representing a location of a guiding point and a navigation message corresponding to the guiding point, from the communication base station; a memory device for storing the guiding information; and a voice processing device for outputting the navigation message in voice format, based on the current location information and the information representing the location of the guiding point which is included in the guiding information.

Navigation apparatus and communication base station, and navigation system and navigation method using same

A signal processing system includes an A/D conversion section for converting an analog signal into a digital signal; a digital signal processing section for processing the digital signal; a D/A conversion section for converting the digital signal into an analog signal; a control section; and a memory section including a first program memory area for storing a program for processing the digital signal and a first data memory area. The digital signal processing section includes a second program memory area connected, via a first bus, to the first program memory area, and a second data memory area connected to the first data memory area via a second bus.

Sound processing system

A semiconductor memory device includes: a plurality of memory cell regions, each comprising at least one memory cell; a non-volatile memory section which accepts external writing; and unselecting means for designating at least one of the plurality of memory cell regions to be inaccessible based on data written to the non-volatile memory section. At least one operation type is performed for at least one accessible memory cell region, which is not designated to be inaccessible, among the plurality of memory cell regions.

Semiconductor memory device and restoration method therefor

A switching transistor is provided which applies predetermined voltage to a plurality of word lines based on a predetermined signal from a power on reset circuit, until predetermined potential becomes stable, when the predetermined potential is applied to the bit line or to the plate line, such as at the time of power on, to connect the bit line connected to each memory cell and the memory cell capacitor, as well as applies a control signal to the gate to thereby electrically connect the bit line and the plate line.
