Abstract: A test apparatus for testing integrated modules has a plurality of connection locations on a carrier substrate. An integrated module may be connected, via a connection location, to a test unit connected to the carrier substrate. The connection locations are arranged in groups within a connection array. A control terminal via which an integrated module may be selected for a test can be provided for each connection location. An address and command terminal can be provided for each connection location. The modules of the number of groups, which are simultaneously operated, are connected to the address and command bus via the respective switching means or switch. The test frequency can thus be increased without adversely affecting the driver load.

Abstract: An integrated semiconductor memory includes at least one word line and a number of memory cells. Each memory cell has a selection transistor coupled to the word line. A word line driver is coupled to the word line. The word line driver provides a first electrical potential or a second electrical potential to the word line such that the word line is activated by the first electrical potential and is deactivated by the second electrical potential. A passive component (e.g., a diode or a resistor) is coupled between the word line and the second electrical potential such that the word line is coupled to the second electrical potential in a high-resistance fashion through the passive component. The passive component is transmissive for a leakage current between the word line and the contact connection.

Abstract: An integrated semiconductor memory can be operated in a normal operating state synchronously with a control clock. In the test operating state, the integrated semiconductor memory is driven synchronously with a clock edge of the control clock with a first control signal and starts a test run independent of the control clock. Driving with the first control signal, selection transistors in a memory bank that can be selected by a memory bank address are turned off. Afterward, bit lines in the selected memory bank are interconnected and driven with a predetermined precharge potential. After a precharge time has elapsed, one of the word lines is selected by an applied word line address and the selection transistors in the selected memory bank connected to the selected word line are turned on. Precharge times are set and tested independently of the clock period of the control clock.

Abstract: An integrated circuit includes an input terminal (IN) for application of a supply voltage (Vext) and an output terminal (A) for generation of an output voltage (Vout). A first branch including a first controllable resistance (T1) and a second branch including a charge pump (10) and a second controllable resistance (T2) are connected between the input terminal (IN) and the output terminal (A). A control circuit (20) alters the resistance values of the first and second controllable resistances (T1, T2) in a manner dependent on a ratio of an actual value (Vout) of the output voltage to a desired value (VSout) of the output voltage and a ratio of an actual value (Vext) of the supply voltage to a desired value (VSext) of the supply voltage. As a result, the output voltage (Vout) can be stabilized to the desired value (VSout) virtually independently of fluctuations of the supply voltage.

Abstract: An integrated semiconductor memory includes a memory cell array with at least one memory cell, in which a data value is stored, and an evaluation circuit with a counter. During a test of the integrated semiconductor memory, a counter reading of the counter is altered if the data value stored in the memory cell deviates from a desired value. A threshold value is predefined by a control circuit. A programming circuit compares the threshold value on the input side with the instantaneous counter reading of the counter. If the counter reading of the counter exceeds the threshold value, a programming element changes from a first programming state to a second programming state. After the conclusion of the test, the state of the programming element is read out via an output terminal. This scheme makes it possible to deduce a possible cause of failure of the integrated semiconductor memory.

Abstract: In an arrangement for determining a temperature loading during a soldering process, a semiconductor chip (1) comprises at least one contact (2) to be soldered or is electrically conductively connected to at least one contact (14d) to be soldered that is situated outside the semiconductor chip. The semiconductor chip (1) furthermore comprises a temperature sensor device (3), which determines a measurement quantity corresponding to the temperature. A processing device (4, 5) has an analog-to-digital converter (5), which is electrically conductively connected to the temperature sensor device (3) and converts the measurement quantity into at least one storable signal that represents the temperature loading. A voltage supply device (10), which is electrically conductively connected to the temperature sensor device (3) and the processing device (4, 5), supplies these components with an operating voltage. A data memory (6) serves for storing the at least one storable signal.

Abstract: Semiconductor memories (1) have segmented word lines (5a, 5b), which in each case have a main word line (10a, 10b) made of a conductive metal and a plurality of interconnect segments (15a, 15b) coupled to the main word line (10a, 10b), which are coupled to the respective main word line (10a, 10b) in each case via at least one contact hole filling (11). If one of the contact hole fillings (11) is defective or at high resistance then functional errors of the semiconductor memory occur. The interconnect segments (15a, 15b) of two respective word lines (5a, 5b) can be short-circuited in pairs with the aid of switching units (20), whereby a static current (I) that flows via the contact hole fillings (11) can be used for electrically stressing the contact hole fillings (11). Electrical stressing of contact hole fillings of segmented word lines is thus made possible.

Abstract: An integrated semiconductor memory device includes a memory cell array (B1) with a first bit line and a second bit line (BL, /BL), a controllable resistor (SW) and a control unit (100) configured to control the controllable resistor. In a first operating state of the integrated semiconductor memory device, the first and second bit lines are connected to one another via a first controllable switch (ET1) and also via the controllable resistor (SW) which has been set to a low resistance, to a connection (A10) that applies a mid-voltage (VBLEQ), where the voltage level of the mid-voltage is in the form of an arithmetic mean between a first and second voltage potential (VBLH, VBLL). By virtue of the control unit briefly setting the controllable resistor to a very low resistance in the first operating state of the integrated semiconductor memory device, the period of time required for the first and second bit lines require to assume the mid-voltage (VBLEQ) is shortened.

Abstract: A voltage generator arrangement supplies a largely constant output voltage with a high current driver capability. A bandgap reference circuit drives a voltage generator on the output side, if necessary via an impedance converter. The bandgap reference circuit and the impedance converter on the one hand, and the voltage generator on the other hand, are connected to different reference ground potential lines. The voltage generator on the output side is preceded by a correction circuit, which corrects for the voltage drop on that reference ground potential line to which the output-side voltage generator is connected. The voltage generator arrangement is suitable for a greater integration density.

Abstract: An integrated memory has a memory cell array having word lines and bit lines. The bit lines are organized in bit line pairs. The bit lines of the bit line pairs cross one another at a crossing location and run parallel to one another. A sense amplifier is connected to one of the bit line pairs at one end. Two precharge circuits are provided. One precharge circuit is arranged on a side of the crossing location and the other precharge circuit is arranged on a side of the crossing location. The precharge circuit facing the sense amplifier is arranged at a first distance from the crossing location and at a second distance from the sense amplifier. The RC constant of the bit lines, which is effective during the precharge operation, is reduced, so that the time period required for a precharge operation is reduced.

Abstract: An integrated circuit includes a programming circuit (10) for generating programming signals (PS1, . . . , PS4) with a first input terminal (E1) for applying a control voltage (ES), a second input terminal (E2) for applying a reference voltage (Vref), a storage circuit (30) with programmable switches (35, . . . , 38) and output terminals (A1, . . . , A4). The programming circuit in each case generates a programming signal (PS1, . . . , PS4) when the control voltage (ES) exceeds a predefined threshold voltage formed from the reference voltage. The number of programming signals (PS1, . . . , PS4) is dependent on the magnitude of the threshold voltage exceeded by the control voltage (ES). The programming signals are used for programming the programmable switches (35, . . . , 38). The programming state of the programmable switches can be read out via the output terminals (A1, . . . , A4) of the integrated circuit.

Abstract: A voltage generator arrangement supplies a largely constant output voltage with a high current driver capability. A bandgap reference circuit is downstream from an impedance converter and downstream a voltage generator. The bandgap reference circuit and the impedance converter on the one hand and the voltage generator on the other hand are connected to different reference ground potential line. The impedance converter contains a charge pump circuit to provide increased control potential, which drives the voltage generator. The voltage generator in contrast produces a reduced output potential. The influence of any voltage drop on that reference ground potential line to which the voltage generator is connected in the output potential is thus likewise reduced.

Abstract: A circuit for controlling an access to an integrated memory includes a command decoder for receiving at least one external command for an access to the memory. An access controller is connected to the command decoder for receiving internal command signals, which are output by the command decoder. In the course of a memory access, the command decoder outputs a precharge command signal for precharging a row of the memory cell array of the integrated memory. A control circuit, which can determine a temperature of the memory, is designed to temporally variably influence the transmission of the precharge command signal of the command decoder to the access controller in a manner dependent on the temperature of the memory. The write recovery time tWR can be retained even for higher operating frequencies of the memory.
