The invention proposes an apparatus for writing to and/or reading from a memory cell in a semiconductor memory having a selection transistor and a storage capacitor, where the apparatus has a device which is used to influence a threshold voltage for the selection transistor contrary to the influence of an ambient temperature. The invention also proposes a method for writing to and/or reading from a memory cell in a semiconductor memory having a selection transistor and a storage capacitor, where the method comprises the following method steps: a) an ambient temperature for the memory cell is ascertained, and b) an electrical voltage is applied to a substrate well in the selection transistor as a function of the ascertained ambient temperature such that a threshold voltage for the selection transistor is influenced contrary to the influence of an ambient temperature.
