Abstract
An integrated memory has two first switching elements, which respectively connect a bit line of a first bit line pair to a bit line of a second bit line pair. In addition, the integrated memory has two second switching elements, which respectively connect one of the reference cells of one bit line pair to that bit line of the other bit line pair which is not connected via the corresponding first switching element to the bit line assigned to this reference cell. Information is written back to the reference cells via the sense amplifiers. A method of operating the integrated memory is also provided.
