ABSTRACT:
An integrated semiconductor memory device includes external terminals to which an input signal can be applied to each external terminal, and a register circuit with registers. Each register stores a respective input signal. A programming circuit is also provided with programmable switching units configured such that, in a manner dependent on a respective programming state of the programmable switching units, each respective external terminal can be connected to a respective register of the register circuit. The programming circuit can be programmed by applying unit vectors of programming signals alternately to the external terminals. In this case, the programming signal having a first state is applied in each case to one of the external terminals and the programming signal having a second state is applied to the rest of the external terminals. The integrated semiconductor memory makes it possible for an unknown line scrambling to be resolved internally.
