An integrated semiconductor memory can include a plurality of subcircuit blocks arranged on nonoverlapping area sections. The subcircuit blocks each have a block supply line and a block ground line, which supply individual switching elements of the subcircuit blocks with a voltage. Each block supply line and block ground line is connected to a chip supply line and a chip ground line, which run outside the area sections of the subcircuit blocks. At least one connection between the chip supply line and the block supply line of at least one subcircuit block or between the chip ground line and the block ground line of at least one subcircuit block can be isolated by a switching device. Furthermore, a method for reducing leakage currents in a semiconductor memory, which, depending on the operating state of the semiconductor memory, isolates or connects individual subcircuit blocks of the semiconductor memory from or to a voltage supply.

In the method for modifying a default time duration between an execution instant of a second operation and an earlier execution instant of a first operation executed earlier in a memory element, wherein the memory element is operable in a test operation mode and a normal operation mode, at first a real time duration in the memory element is determined and provided during the test operation mode, wherein the real time duration is chosen so that a performance parameter of the memory element, when using the real time duration between the execution instants of the first and second operations, improves over a situation in which the default time duration between the execution instants of the first and second operations is used. Then, the default time duration is changed in direction of the real time duration during the test operation mode to obtain a modified default time duration. Then information on the modified default time duration or on the ascertained real time duration are stored in the memory element during the test operation mode, wherein the second operation is executed offset by the modified default time duration after the execution instant of the first operation during the normal operation mode.

Integrated circuits are tested on the wafer level through an additional circuit part that is electrically connected via at least one connecting line with the associated integrated circuit. The additional circuit part is integrated into an interspace between the integrated circuits of the wafer. Functions of the integrated circuit can be controlled via the connecting line. For example, in the case of a memory module such as a DRAM, internal voltages and/or currents of the integrated circuit can advantageously be measured even on internal lines which are otherwise only accessible with difficulty. Following the wafer-level testing and dicing of the integrated circuits into individual chips, the additional circuit part becomes unusable.

A transistor configuration for a bandgap circuit is configured in the form of an npn transistor. An insulated p-type well, which is surrounded by a buried n-type well, is used as a base terminal. The n-type well constitutes the emitter terminal. A negatively doped region, which acts as a collector terminal, is formed in the p-type well. The structure that is used exists in DRAM processes, and it can therefore be used to form an npn transistor as a footprint diode in bandgap circuits.

A semiconductor memory is described which has a clock input, a signal input, a data output, a measuring device, a control circuit, and a latency. The latency elapses between the activation of the signal input and the availability of the data to be read at the data output. A clock signal is fed to the clock input. On the basis of the clock signal, the measuring device determines a value for the latency and the control circuit configures the semiconductor memory with the determined value for the operation of the semiconductor memory.

An integrated memory has a memory cell array, which is subdivided into a plurality of separate segments. A first and a second local word line in different segments together form a common global word line. The global word line is decoded via a row decoder. The first and second local word lines are connected to a column decoder in such a way that they can be decoded individually and segment by segment in a manner dependent on a column address. The memory thus allows fast and current-saving activation of a word line.

A circuit configuration for deactivating word lines in a memory matrix. The circuit configuration contains controllable connection devices for connecting the relevant word line to a common supply line system carrying the deactivation potential for the word lines. The circuit configuration contains a control circuit that, in response to a deactivation command, produces a deactivation control signal that turns on the controllable connection devices. A reduction device is provided which can be switched on selectively and which, when switched on, limits the currents flowing through the turned-on connection devices to such an extent that the total current flowing via the supply line system does not exceed a prescribed value.

The invention relates to a fusible link configuration in or on integrated circuits, in particular highly integrated memory chips, in which in each case one bank of fusible links (F1, F2, . . . ), together with an evaluation logic unit is configured beside and in association with a memory field segment. The evaluation logic unit is electrically connected to the fusible links (F1, F2, . . . ) and determines whether one or more of the fusible links (F1, F2, . . . ) is severed. One or more banks of the fusible links (F1, F2, . . . ) are divided up into smaller units while restricting the width(s) of the bank or banks. The units are grouped such that at least some of the fusible links (F1, F2, . . . ) are located beside one another transversely with respect to the width direction of the bank.

The invention relates to a lockable glove and auxiliary compartment cover system for motor cars having a lock which is transferable into its tripping position by the stressing of a tripping lever by means of an actuating element. A closing member is provided which can be rotated between positions permitting and blocking the operative connection between the actuating element and the lock to change the security condition of the system. The change of the security condition occurs by means of a toothed-wheel gear which comprises a spur gear element rotatable with the closing element and a further gear element meshing with the spur gear element. In order to permit a handier arrangement of the actuating elements, the further gear element is likewise constructed as a rotatably mounted spur gear element, at least one of the spur gear elements, which belongs to a push-button, is guided for axial sliding, and a tripping stud protrudes eccentrically from the spur gear elements guided for axial sliding by means of which the tripping lever is pivotable in order to trip the lock.
