Abstract

An integrated memory has a memory cell array with row lines and column lines. A row decoder for activating row lines is connected to address lines for transferring address signals. A voltage regulating circuit serves for applying a regulatable supply voltage to one of the row lines. For the purpose of setting the supply voltage, a driving circuit is connected to the address lines and to the voltage regulating circuit. This enables trimming of the voltage regulating circuit in conjunction with a comparatively small area requirement.
