Abstract
In one embodiment, a readout circuit for rewritable memories comprises a control logic unit with an input for supplying a start signal and with several outputs for providing a respective control signal as a function of start signal, a first terminal for switchable connection to a first memory cell by means of a first switch, and a second terminal for switchable connection by means of a second switch to a second memory cell, and a readout unit coupled to the control logic unit, as well as to the first and second terminals, with an output for providing an output signal as a function of a state of the first and/or the second memory cell and as a function of the control signals, wherein the readout circuit is designed for self-terminating operation in a reading mode and in a test mode. A readout method for rewritable memories is additionally provided.
