Abstract: An integrated semiconductor circuit is described and has a semiconductor memory configuration embedded in a semiconductor chip and an interface circuit. The interface circuit is set 5 up for the connection and transfer of data and control signals between the semiconductor memory configuration and a circuit periphery surrounding the memory configuration. The interface circuit is configured as a standard interface for all types of integrated semiconductor circuits with an embedded semiconductor memory configuration for the largest bit width that can be realized in the semiconductor memory configuration. A switch configuration is provided which switches off bits of the standard interface that are unused for smaller bit widths.

Abstract: A method for fabricating a field-effect transistor situated within an integrated semiconductor circuit. At least two gate regions each extending between a source region and a drain region and are disposed such that they lie one above the other in a thickness direction of a substrate, thereby reducing the space requirement of the hitherto customary larger field-effect transistors in integrated semiconductor circuits.
