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 operating property of the integrated circuit, such as its speed class, value is determined during testing. In order to identify the integrated circuit with a value for its operating property, there are provided at least two registers whose outputs are logically combined bit by bit via OR gates. The registers are preferably programmable with fuses. In a first test run, the first register is programmed with the ascertained value of the operating property, and the second register is correspondingly programmed in a second test run. The logic combination enables the less significant value of the operating property to predominate. The storage of this value on the integrated circuit itself simplifies the later identification on the housing of the integrated circuit.

Abstract: An integrated memory has a plurality of memory cell arrays. The memory cell arrays are in each case assigned a decoder for selecting bit lines and word lines. In order to trigger an access cycle for a memory cell access, a write command or a read command with an active state is generated. Within the access cycle, under the control of a control circuit, respective decoders of the memory cell arrays are driven and data of each of the memory cell arrays are successively read out or written in for as long as the read command or write command remains in the active state. As a result, it is possible to set a comparatively large variable burst length of the memory. A method for operating an integrated memory is also provided.

Abstract: A circuit configuration for providing a capacitance includes short-channel MOS transistors that are reverse-connected in series or in parallel, and that have the same channel type. When the short-channel MOS transistors are operated exclusively in the depletion mode in the required voltage range, the useful capacitance is increased, because of intrinsic capacitances, as compared with circuit configurations having conventional long-channel MOS transistors. These circuits greatly reduce the area taken up and reduce the costs.
