Title: Analog switch
Inventor: YAZAWA NOBUHARU
IPC: H03K17/60
Filed: 1979-05-30
Abstract: PURPOSE: To obtain less distortion and to avoid the production of transient sound at switching, by the constitution that the output terminals of two amplifiers which are switched and controlled with control signals in opposite phase with each other are commonly connected.  
     CONSTITUTION: The input of an amplifier A 1  is connected to a bias voltage VR and that of an amplifier A 2  is also connected, and a signal Va is superimposed on the terminal A and the respective output is commonly connected at the terminal B. On the other hand, a control signal V c  and inversion V c  are respectively driven in opposite phase, and when the amplifier A 1  is closed, the amplifier A 2  is open, and while the amplifier A 1  is opened, then the amplifier A 2  is closed. Thus, only the voltage VR is obtained at the terminal B when the amplifier A 1  is closed and the signal Va is superimposed on the voltage VR when the amplifier A 2  is closed and no DC potential fluctuation is present. Accordingly no noise is produced at switching.

Title: Semiconductor storage device
Inventor: OKIDAKA TAKENORI
IPC: G11C11/409
Filed: 1990-03-20
Abstract: PURPOSE:To reduce the power consumption at the time of reading out data and to execute the operation at a high speed by activating a pre-charge means only in a period in which the corresponding read-out bit line is selected. CONSTITUTION:Gates of pre-charge transistors 7 are connected to output terminals A0 - An of an address pointer 114 together with gates of the corresponding read-out bit line access transistors 8a, 8b. A read-out word line 6 selected at the time of reading out data synchronizes with a rise of a clock signal RCK and becomes an 'H' level only for one period of the read-out clock signal RCK. Accordingly, in a period in which data is read out from an arbitrary memory cell 1 in which storage data is 'H', a through current flows through the corresponding pre-charge transistor 7 to only a read-out bit line 4 connected to this memory cell, and the through current does not flow to other read-out bit line 4. In such a way, the operation can be executed at a high speed by low power consumption.
