The invention relates to an integrated circuit arrangement with connection contacts for the serial exchange of data and/or signals with external components and apparatuses and with a control apparatus and/or a serial interface for the clocked receiving of data by means of a signal voltage on such a connection contact, which voltage is modulated between at least one low, one middle and one high voltage state. The control apparatus and/or the interface are designed in such a manner that data is sent in a sending mode via the connection contact in that the switching apparatus, after having received a slope changing in particular from the middle voltage state into in particular the higher or the lower voltage state, pulls the voltage state into the in particular opposite lower or higher voltage state. Furthermore, the invention relates to an apparatus and a process for operating such a circuit arrangement.

Circuit arrangement, apparatus and process for the serial sending of data via a connection contact

An integrated circuit comprising at least one group comprising having multiple arithmetic/logic units arranged in sub-groups. In the sub-groups at inputs of multiple arithmetic/logic units, in each case a single one of the first selection units is connected on the input side, wherein no other selection unit is connected directly on the input side of this selection unit. The first selection units are coupled to each other such that a horizontal and/or vertical logical interconnection of the arithmetic/logic units within a group, and/or a logical interconnection of arithmetic/logic units to an upstream group can be implemented. Second selection units are in each case connected on the output side of a column of arithmetic/logic units. The second selection units of a group are connected on the output side to one bus each, and a microprocessor is coupled to this bus.

Circuit architecture for an integrated circuit

A storage control for implementing switching commands for access to storage cells for writing or reading data receives control commands which are allocated to the data. The storage control has a command set for at least one memory type with command sequences of individual switch commands to be processed in a predetermined succession, which are activated by the control commands one after another at a predetermined time after the activation of the preceding switch command. Here, depending on the previous switch command and the current control command, there is created an activation command, which activates the current switch command. Moreover, the storage control contains information items allocated to the storage cells which indicate the predetermined time for the respective switch command.
