Integrated semiconductor configuration having a semiconductor memory with user programmable bit width

An integrated semiconductor circuit, comprising:

• a semiconductor chip;
• a semiconductor memory configuration having different bit widths embedded in said semiconductor chip;
• a circuit periphery embedded in said semiconductor chip and surrounding said semiconductor memory configuration;
• and
• an interface circuit disposed on said semiconductor chip for connecting and transferring data and control signals between said semiconductor memory configuration and said circuit periphery, said interface circuit being a standard and identical interface for all types of integrated semiconductor circuits having said semiconductor memory configuration, said standard interface configured for interfacing with a largest bit width to be realized in said semiconductor memory configuration, said interface circuit having a switch configuration switching off unused bits of said interface circuit for defining smaller bit widths.
