Abstract: A digital memory circuit contains a plurality of areas each having memory cells disposed in matrix form in rows and columns. The columns of each memory area is subdivided into a plurality of adjacent groups which each form a segment. For each segment, provision is made of a separate set of two-conductor local data lines which lead via line switches to two-conductor master data lines common to all the memory areas. Furthermore, precharge devices are provided in order to equalize the potentials of the conductors of the local data lines and the conductors of the master data lines, the equalization potential for the local data lines being different than the equalization potential for the master data lines. A line switch control device provides for closing only of the line switches on those local data lines which belong to the segment in which a write or read mode takes place.

Abstract: An integrated circuit has a differential amplifier in a basic circuit having two input transistors, a load element and a power source. The power source has an N-type channel MOS transistor whose controlled path is connected to the input transistors and to a supply terminal of the power source. A control terminal of the transistor is connected to a potential that is positive with respect to a reference potential. The supply terminal of the power source is connected to a potential which is negative with respect to the reference potential and which is made available by a voltage source for switching off cell field transistors of a DRAM memory. The gate-source voltage that is increased in this way improves the behavior of the circuit with respect to fluctuations in potential and permits more favorable dimensioning of the transistor.

Abstract: An integrated dynamic semiconductor memory has memory cells which are provided in a matrix-like memory cell array and are combined to form units with column lines and row lines. The integrated dynamic semiconductor memory has a decoder for selecting one of the column lines and a sense amplifier which is jointly allocated to all the memory cells in a selected column line. The sense amplifier is connected to a data signal line for the purpose of further processing a data signal from an addressed memory cell. The decoder for selecting one of the column lines and the sense amplifier are provided at the edge and on opposite sides of the memory cell array. By separating the control for selection of the column lines and of the data output path, successive steps in the process of read access can be controlled in a self-adjusting manner by the respective preceding signal.

Abstract: A dynamic semiconductor memory device of the random access type having an initialization circuit which controls the switch-on operation of the semiconductor memory device and of its circuit components. The initialization circuit supplies a supply voltage stable signal once the supply voltage has been stabilized after the switching-on of the semiconductor memory device. The initialization circuit has an advance detector circuit, which detects a predetermined level state of an externally applied clock control signal chronologically before the supply voltage stable signal is generated and, as a reaction to this, supplies a first enable signal for unlatching the control circuit provided for the proper operation of the semiconductor memory device.

Abstract: A long arm bears a probe at its end and is arranged in such a way that it can swivel by small angular amounts. This low-mass and slowly movable system is protected by a protective device from which it emerges only partly during the measuring operation. A lowering device which both decouples and entrains, interacts with a damping element. An article to be measured is pushed onto the protective device, an actuating device is pressed and the probe slowly emerges from the protective device and ultimately rests in a defined manner and with adequately low force on a layer of the article.
