ABSTRACT:
The present invention relates to a memory circuit comprising a CBRAM resistance memory cell, which is connected to a bit line and a word line and has a CBRAM resistance element, the resistance of which can be set by means of a write current, in order to store an item of information, and which has a selection switch, which can be driven via the word line, in order to connect a first potential to the bit line via the CBRAM resistance element; a reference resistance cell, which is connected to the bit line and to a reference line and has a reference resistance element, the resistance of which is set to a resistance threshold value, and a reference selection switch, which can be driven via the reference line, in order to connect a second potential to the bit line via the reference resistance element; a read-out unit, which is configured to activate the reference selection switch and the selection switch for the purpose of reading out a memory datum, so that a memory cell current flows via the CBRAM resistance memory cell and a reference current flows via the reference resistance cell onto the bit line; and an evaluation unit, which is connected to the bit line, and which outputs the memory datum in a manner dependent on a resulting electrical quantity assigned to the bit line.
