The MRAM includes: a memory cell 10 including a magnetoresistance element 1, a current supply circuit and a controller. The method also includes sampling the output signal to generate data values and an error value, each data value comprising either a high value or a low value based on the sampling of the output signal, the error value indicating residue of the distortion based on the sampling of the output signal. A pressure balloon to which pressure fluid can be admitted may be arranged in the interior of the supporting implant for producing the internal pressure.
