A circuit arrangement for setting a voltage supply for a read/write amplifier of an integrated memory has a first voltage generator circuit for generating a supply voltage for application to the read/write amplifier during an assessment and amplification operation and a second voltage generator circuit for generating a precharge voltage for precharging bit lines of the memory which are connected to the read/write amplifier. A temperature detector circuit, which is connected to the first voltage generator circuit, is used to detect a temperature of the memory and interacts with the first voltage generator circuit to set the supply voltage applied to the read/write amplifier in a manner depending on a temperature of the memory.
