ABSTRACT:
A read-out circuit is disclosed, where the circuit reads information out of a memory unit comprising two non-volatile memory cells. The cells have different programming states, and the memory information of the memory unit is given by the programming states of the two memory cells. The read-out circuit has a volatile signal memory, the inputs of which are connected to the read outputs of the memory cells.
