For readout circuit, which can be described again, memory and reading-out techniques for the same

摘要

The readout circuit for rewritable memory comprising:— a control logic (sl) having an input for supplying a start signal (start) and with a plurality of outputs for providing in each case of a control signal as a function of the start signal (start),— a first terminal (21) for the switchable connection by means of a first switch (s1) with a first memory cell (140), and a second connector (22) for the switchable connection by means of a second switch (s2) with a second memory cell (130),— a with the control logic (sl), as well as with the first and the second terminal (21, 22) coupled to the readout unit (corresponding, av), with an output (23) for providing an output signal (out) as a function of a state of the first and / or the second memory cell (140, 130), and as a function of the control signals,wherein the readout circuit, in each case for itself, in a terminated and that is designed in a test mode, andthe read-out circuit for rewritable memory, in which a data bit is formed by two memory cells,..
