Abstract
An integrated memory having a memory cell array with addressable column lines and addressable row lines is described. The memory further has a charge equalization device for charge equalization on the column lines, and an amplifier circuit connected to the column lines. A control device drives the charge equalization device after the activation of an addressed row line for writing to a memory cell, so that charge equalization is carried out on an addressed column line. Furthermore, the control device is connected to the amplifier circuits to switch the amplifier circuits on and off. After the activation of the addressed row line, the amplifier circuit on the addressed column line is switched off during a write procedure. Afterward, the charge potential on the addressed column line is equalized by the charge equalization device. Afterward, the amplifier device is switched on for writing the datum to the addressed memory cell.
