Abstract: In one embodiment, the current source arrangement comprises a current source (B), that has two output terminals (102, 103) and a control input (101) to be supplied with a control voltage (Vgs) and is set up to provide a current (I) as a function of a voltage (Vds) at the output terminals (102, 103) and the control voltage (Vgs), an operating point adjustment unit (E) that is supplied with an actual value (Vi) proportional to an actual value of the current (I) and is set up to provide the control voltage (Vgs) as a function of the actual value (Vi) and a predetermined target value (Iz) of the current (I), and a comparison unit (A) coupled to the control input (101) of the current source (B) for providing a monitoring signal (100), wherein the monitoring signal (100) is provided as a function of a predetermined limit voltage (VG) and the control voltage (Vgs). A method for operating a current source arrangement is also specified.

Abstract: A circuit arrangement comprises a memory cell array (2) with at least one memory circuit (99). The memory circuit (99) comprises one non-volatile memory cell (98) inserted in a first current path (106) between a supply voltage terminal (9) and a reference potential terminal (8), and a volatile memory cell (97) inserted in a second current path (107) between the supply voltage terminal (9) and the reference potential terminal (8). The volatile memory cell (97) is coupled to the non-volatile memory cell (98) for reading the non-volatile memory cell (98).

Abstract: The circuit arrangement comprises a symmetrically constructed comparator (3), a non-volatile memory cell (10) and a reference element (20). The comparator (3) exhibits a latching function, and is connected in a differential current path that joins the power supply terminal (9) to a reference potential terminal (8). The non-volatile memory cell (10) is connected in a first branch (35) of the differential current path, and the reference element (20) is connected in a second branch (55) of the differential current path.
