Title: Semiconductor memory device
Inventor: KAWADA KOJI
IPC: H01L27/04
Filed: 1988-09-28
Abstract: PURPOSE:To enable the reduction of erroneous operation of a memory cell at the end of a memory cell block by a method wherein the capacitance of a dummy cell air each end of a memory cell block is made smaller than that of other dummy cells. CONSTITUTION:The width of a capacitive polysilicon film 7'-1, which is made to serve as one electrode of a dummy cell DC' connected to a data line D, is made smaller than that of others. Concerning a dummy cell connected to a data line D', the same process is taken as above. Thereby, the capacitance of the dummy cell arranged at the end of a memory cell block becomes smaller than that of other dummy cells. Therefore, a margin is assured on a cell 'L' side so as to prevent a memory device from deteriorating in level due to the fluctuation of a power voltage and a ground potential and noises. By this setup, the erroneous operation of a memory cell at the end of a memory cell block can be reduced and a semiconductor memory device can be improved in yield.

Title: Automatic gain control amplifier
Inventor: WASHIMI KAZUYUKI
IPC: H03G3/20
Filed: 1984-11-20
Abstract: PURPOSE:To suppress saturation of the 1st part of a waveform by connecting an additional circuit comprising a diode and a variable resistor to a charge/ discharge circuit having a proper time constant and giving a constant voltage level set by the variable resistor via the diode when a hold voltage is a prescribed level or below so as not to bring the gain of an amplifier to a value or over. CONSTITUTION:A control voltage VC fed to a gain control terminal of an amplifier 1 is a larger voltage between a hold voltage VH of an output waveform and a constant voltage by a variable resistor VR and the control voltage VC fed to the amplifier 1 is held to a proper voltage or over by setting the variable resistor VR to a proper value. Thus, the gain of the amplifier 1 is suppressed to a proper value or below. Further, when a signal input is small, the controlvoltage VC of the amplifier 1 is made constant by the additional circuit 3 and the gain is constant until the constant voltage by the variable resistor VR shown in figure is exceeded. Thus, the gain of a small input is set optionally by adjusting the VR.
