Integrated memory having memory cells with magnetoresistive storage effect

摘要

The integrated memory has memory cells with a magnetoresistive storage effect in a memory cell array in the form of a matrix. The memory cells are each connected between one of the column lines and one of the row lines. The column lines are each connected to a read amplifier for reading a data signal from a memory cell. The read amplifier has an operational amplifier with feedback, and a first control input connected to one of the column lines. A capacitor is connected between a second control input of the operational amplifier and a terminal for a supply potential and is used to compensate for any offset voltage at the control inputs of the operational amplifier. This allows a data signal which is to be read from one of the memory cells to be detected comparatively reliably.
