Title: Semiconductor storage and its driving method
Inventor: IHARA MAKOTO
IPC: G11C17/00
Filed: 1995-10-26
Abstract: PURPOSE: To attain the nonvolatile storage of data by holding a positive or a negative residual dielectric polarization in the ferroelectric film between both electrodes of a capacitor. CONSTITUTION: A memory cell 6 is provided with a capacitor Cs having a ferroelectric film in between electrodes and an N channel type MOS.FET Qs and the electrode of one side of the capacitor Cs is connected to a bit line BLi or the inverse of BLi via the source and the drain of the FET Qs. At the time of a readout, the line BLi being not selected is held at a common cell potential 1/2 Vcc connected to the electrode of the other side of the capacitor Cs of the cell 6. Consequently, even though a word line WL is selected and the FET Qs is turned ON and the electrode of one side is connected to the line BLi, a voltage is not impressed in between electrodes of the capacitor Cs and a residual dielectric polarization stored in the ferroelectric film is held.  Consequently, even though the word line ML is selected, the rewriting after the readout of the memory cell being not selected is urmecessitated. Thus, power consumption of a read and a write operations is reduced.

Title: Stereo reproducing device for television receiver
Inventor: MORI TORU
IPC: H04S1/00
Filed: 1988-11-07
Abstract: PURPOSE:To attain stereo reproduction having the more natural spread of a sound field by respectively connecting low pass filters suppressing the high frequency range of the differential signals of right and left channels for the respective inputs of third and fourth speakers. CONSTITUTION:Speakers 1 and 4 are those to reproduce a sub-sound source by means of the differential signals of the right and left channels, and low pass filters 7 and 8 are serially connected between power amplifiers 5 and 6. In the case of a video source, since the high frequency component of the differential signals of the right and left channels inputted to speakers 1 and 2 is suppressed by the low pass filters 7 and 8, noises can be reduced. In the case of an acoustic source, since the high frequency component only of the differential signal of the right channel inputted to the speaker 1 is suppressed by the low pass filter 7, the differential signal of the left channel is inputted to the speaker 4 as it is, and the high frequency component of the right and left channels can be equalized between the right and left channels. For this reason, the stereo reproduction having the extremely natural sound field is attained.
