Method for operating an integrated memory

An operating method, which comprises the steps of:

• providing an integrated memory having a memory cell array of memory cells, column lines, and row lines, the memory cells have selection transistors and storage capacitors with a ferroelectric storage effect, the integrated memory further having a plate line connected to one of the column lines through a series circuit containing a selection transistor and a storage capacitor of each of the memory cells, the selection transistors have control terminals each connected to a respective one of the row lines, and the memory cells can be accessed in an access cycle;
• prior to an access, setting a column line and the plate line connected to a memory cell to be selected to an initial potential;
• during the access, activating a row line connected to the memory cell to be selected, with a result that the selection transistor of the memory cell is switched on;
• applying a further potential to the plate line, the further potential being different from the initial potential of the column line;
• evaluating and amplifying a potential present on the column line at a first instant;
• applying the initial potential to the plate line at a second instant;
• applying the initial potential to the column line at a third instant;
• and
• choosing the first instant, the second instant and the third instant such that, in the access cycle, the storage capacitor of the memory cell to be selected is in each case charged and discharged by an equivalent amount.
