Title: Circuit and method for controlling an access to an integrated memory

Abstract: A circuit for controlling an access to an integrated memory includes a command decoder for receiving at least one external command for an access to the memory. An access controller is connected to the command decoder for receiving internal command signals, which are output by the command decoder. In the course of a memory access, the command decoder outputs a precharge command signal for precharging a row of the memory cell array of the integrated memory. A control circuit, which can determine a temperature of the memory, is designed to temporally variably influence the transmission of the precharge command signal of the command decoder to the access controller in a manner dependent on the temperature of the memory. The write recovery time tWR can be retained even for higher operating frequencies of the memory.
