For a programmable logic cell, an output assumes a value, which is dependent on values of inputs and on a Boolean function, which determines a value for the output for each setting of the inputs. The logic cell includes at least one ALU and additional logic via which the Boolean function of the logic cell is configurable. In a preferred embodiment, the logic cell contains two 1-bit ALUs and a block generator with four configuration bit memory cells. Here the logic cell can be configured in such a way that it replicates any desired Boolean function with four parameters or any two Boolean functions with two parameters, or is operated in an arithmetic mode.
