Abstract

The integrated memory chip has an external control terminal, a dynamic memory, and a control circuit for controlling a memory access to the dynamic memory. The control circuit is connected to the external control terminal, for receiving an access command indicating the beginning of a memory access. The control circuit further has an output, which is connected to the dynamic memory, for outputting at least one activation signal, read command or write command and precharge command generated from the access command. This makes it possible, in the case of use in a data processing system, to dispense with a DRAM controller provided outside the memory chip.
