Integrated semiconductor memory device

A method for operating an integrated semiconductor memory device, comprising:

• providing an integrated semiconductor memory device including a plurality of external terminals to which an input signal can be applied to each external terminal, a register circuit including a plurality of registers, each register configured to store a respective input signal, a programming circuit including a plurality of programmable switching units that are configured, in a manner dependent on a respective programming state of the programmable switching units, to facilitate a connection between each external terminal and a respective register of the register circuit, the programming circuit being configured such that the programming state of one of the programmable switching units of the programming circuit is programmed by a respective programming signal being applied to the external terminals, the programming signal applied to one of the external terminals having a first state and the programming signals applied to all other external terminals having a second state;
• programming a selected number of programmable switching units that corresponds to the number of external terminals by carrying out a programming step in which the programming signal having a first state is applied to one of the external terminals of the selected number and the programming signal having a second state is applied to the rest of the external terminals of the selected number;
• repeating the step of programming the selected number of programmable switching units such that, upon each repetition of the programming step, the programming signal having the first state is applied to a different external terminal and the programming signal having the second state is applied to the rest of the external terminals until the programming signal having the first state has been applied a single time to each external terminal.
