referring now to the figures of the drawing in detail and first , particularly , to fig1 thereof , there is shown a detail of a circuit configuration of a dynamic memory module 1 . the dynamic memory module 1 has a central control unit 5 which is connected to a plurality of memory blocks 28 , 29 . the memory blocks 28 , 29 are of substantially identical construction and the invention is explained with reference to a first memory block 28 . the first memory block 28 has a first memory array 2 or memory field 2 , a memory access controller with a row access controller 4 and a column access controller 3 . memory cells 32 , which can be accessed via column lines 33 and row lines 34 , are arranged in the first memory array 2 . furthermore , an input / output circuit 9 is provided in the first memory block 28 . the input / output circuit 9 has an input interface 12 via which data can be written into an input memory 11 of the input / output circuit 9 . a global data bus 14 which is connected to a plurality of memory blocks 28 , 29 is provided . the global data bus 14 is connected to the memory access controller 3 and to the input / output circuit 9 via an output interface 13 . the row access controller is connected via a second selection line 17 to the memory array 2 . the column access controller 3 is connected via a first selection line 15 and via data lines 16 to the memory array 2 . the control unit 5 has an output 30 which is connected , on the one hand , to a delay circuit 8 and , on the other hand , to a first control line 6 . the first delay circuit 8 is connected by an output to a second control line 7 . the second control line 7 is routed transversely across the first and second memory blocks 28 , 29 . the second control line 7 is connected to the first access controller 3 . the first control line 6 is connected to a switching unit 10 of the input / output circuit 9 . the switching unit 10 is connected to the input memory 11 via a data line and to the global data bus 14 via the output interface 13 . the second control line 7 is also referred to as a copy line and is embodied essentially in the same way as the global data bus 14 . here , the second control line 7 has essentially the same length , and preferably the same geometric arrangement , as the global data bus 14 . in addition , in one preferred embodiment , the second control line 7 is embodied using the same technology as the data bus 14 . here , the metalization line of the second control line 7 is preferably fabricated from the same material as a metalization line of the global data bus 14 . in addition , the metalization line of the second control line 7 is applied to the same material as the metalization line of the data bus 14 . the object of the identical construction of the second control line 7 to that of the data bus 14 is an embodiment which is virtually identical with respect to the propagation time and capacitance and which is independent of the technology used . this ensures that data which is output by the input / output circuit 9 via the global data bus 14 and routed to the column access controller 3 takes essentially the same time as a control signal which is output to the first access controller 3 by the delay circuit 8 via the second control line 7 . in this way , synchronization is achieved between the propagation time of the data between the input / output circuit 9 and the column access controller 3 , and the control signal between the delay circuit 8 and the column access controller 3 . the delay circuit 8 preferably has the same components which the switching unit 10 has and which bring about a delayed outputting of data from the input memory 11 onto the data bus 14 after the inputting of the control signal at the switching unit 10 . not only are the components preferably identical but the same technology is also preferably used for the construction of the delay circuit 8 as for the construction of the switching unit 10 . the object of the identical embodiment of the delay circuit 8 is to simulate the propagation time which passes between the time at which a control signal arrives at the switching unit 10 and the data of the input memory 11 is output by the switching unit 10 onto the data bus 14 via the output interface 13 . using the same technology ensures that when the technology of the circuit [ sic ] unit 10 changes the technology for the delay circuit 8 is also changed and the propagation time is thus kept identical . the method of operation of the configuration of fig1 is explained in more detail below : if data is to be written into memory cells of the memory array 2 , the row addresses of the memory cells into which data is to be written are defined by the row access controller 4 , and the column addresses of the memory cells into which data is to be written are defined by the column access controller 3 . the writing operation is started by an external write signal , which is received by the control unit 5 . in addition , data is read into the input memory 11 as a function of the external write signal via the input interface 12 . at a predetermined interval from the write signal , preferably two clock periods after the write signal , the control unit 5 outputs a control signal ( wrcas ) via the output 30 . the control signal is fed , on the one hand , to the delay circuit 8 and , on the other hand , via the first control line 6 to the switching unit 10 . in the delay circuit 8 , the control signal is stored for a defined time period and is then output to the second control line 7 . the control signal is fed to the column access controller 3 via the second control line 7 . in parallel thereto , the control signal switches , after being input into the switching unit 10 , a connection between the input memory 11 and the output interface 13 so that the data stored in the input memory 11 is output onto the data bus 14 . the data is fed via the data bus 14 to the column access controller 3 . the signal paths of the control signal and the signal paths of the data are adapted to one another in such a way that first the data is present at the column access controller 3 and then the control signal is fed to the column access controller 3 . when the column access controller 3 receives the control signal , the column access controller 3 loads the data present at the data bus 14 into the selected memory cells via the data lines 16 . so that the data is correctly loaded into the memory cells , it is necessary for the data to be present at the column access controller 3 before the control signal is applied to the column access controller . with reference to fig2 there is shown a schematic overview of the signal paths of the control signal and of the data . the control signal is fed via the output 30 to the switching unit 10 and in parallel to the delay circuit 8 . the line paths are constructed in such a way that the control signal is preferably fed simultaneously to the switching unit 10 and to the delay circuit 8 . the switching unit 10 is connected to the input memory 11 . in a simple embodiment , the switching unit 10 is embodied as a flip - flop , the first control line 6 being connected to a control input and the input memory 11 being connected to an input . after reception of the control signal , the flip - flop switches the connection of the input memory 11 to the output of the flip - flop which is connected to the output interface 13 . the delay circuit 8 is preferably of identical construction to the switching unit 10 . the identity relates both to the components which bring about a delay of the switching operation of the switching unit 10 and to an identical technology used to construct components of the switching unit 10 and the components of the delay circuit 8 . the output of the delay circuit 8 is connected to the second control line 7 . both the data bus 14 and the second control line 7 are connected to the column access controller 3 . the data bus 14 is connected to a write amplifier 18 . the column access controller 3 has , in addition to the write amplifier 18 , a selection circuit 19 which is connected to the second control line 7 and to an address input 20 . the selection circuit 19 has , as output , a third control line 21 which is connected to a control input of the write amplifier 18 . if the selection circuit 19 receives a control signal and if a control signal is present simultaneously at the address input 20 , a control signal is output to the write amplifier 18 via the third control line 21 . if the write amplifier 18 receives a control signal via the control input , the write amplifier 18 reads the data present on the data bus 14 in and passes them on to the memory cells of the memory array 2 via the data line 16 . [ 0035 ] fig3 shows the synchronization of the individual control signals in the form of a timing diagram . in the top line a ) of the diagram , a write signal 31 is illustrated which is applied to the control unit 5 at the same time as a rising edge of the internal clock signal 22 . the internal clock signal 22 is illustrated in a second line b ) of the diagram . after this signal information has been detected , the control unit 5 outputs a control signal 23 via the output 30 two clock cycles later at the time t 1 . the control signal 23 is illustrated in a third line c ) of the diagram . the control signal 23 is synchronous with the internal clock signal 22 . in a fourth line d ) of the diagram , a delayed control signal 24 , such as is present at the column access controller 23 , is illustrated . in a fifth line e ) of the diagram , a data input signal 25 is illustrated which corresponds to the control signal at the input of the input / output circuit 9 . if the data input signal 25 has a low level , the switching unit 10 is opened and there is no connection between the input memory 11 and the data bus 14 . when there is a high signal of the data input signal 25 , the switching unit 10 is closed and the input memory 11 is connected to the data bus 14 . the data stored in the input memory 11 is / are transferred onto the data bus . in a sixth line f ) of the diagram , a data bus signal is illustrated which displays the occupation of the data bus 14 with correct data signals . if the data bus signal 26 has a low level , no correct signal levels are present on the data bus 14 . if the data bus signal 26 exceeds a signal edge center at the time t 2 , correct data is present on the data bus 14 . in a seventh line g ) of the diagram , a transfer signal 27 is illustrated . the transfer signal 27 shows with a low level that no data is transferred into the memory access controller 3 . a high level of the transfer signal 27 shows the state wherein correct data has been transferred from the data bus 14 into the column access controller 3 . two clock periods after the write signal , the data input signal 25 ( dqs ) which is fed to the input / output circuit 9 is generated . at the rising edge of the data input signal , data is read out via the output interface 3 and is applied to the column access controller 3 via the data bus 14 at the correct time , i . e . before the second clock period after the write signal at the time t 2 . owing to the delay of the control signal via the delay circuit 8 and the second control line 7 , the delayed control signal 24 is not present at the column access controller 3 until the time t 3 . at the time t 3 , the data is connected to the data bus 14 in a stable state . this is indicated by a high level of the data bus signal 26 . after the reception of the control signal , the data present on the data bus 14 is stored in the selected memory cells by the column access controller 3 by means of the write amplifier 18 .
