ABSTRACT:
A circuit configuration for driving a programmable link has a drive circuit for the selection and blowing of the fuse, and also a shift register, by which an activation signal can be fed to the drive circuit. In order to provide the data to be blown, in a preferred embodiment, a volatile memory cell may be provided. The present circuit configuration enables the blowing of fuses and thus repair of defective memory cells in mass memories even after encapsulation of a chip having the mass memory. Moreover, the shift register described effectively prevents impermissibly high currents from being able to occur as a result of simultaneous blowing of too many fuses.
