Abstract

A circuit configuration for driving a programmable link has a volatile memory cell, which is coupled to the fuse for the permanent storage of data stored in the volatile memory, and also a shift register, which enables data to be read out from the volatile memory cell and data to be written to the memory cell. In this case, a plurality of shift registers may be interconnected to form a shift register chain for the purpose of driving a plurality of fuses. The shift register chain thus enables fast writing and reading to/from the volatile memory with a low outlay on circuitry.
