Abstract

Data transfer is effected on an internal and/or on an external transfer path with or in a semiconductor component, such as a semiconductor memory. A first multiplexer/demultiplexer codes a data sequence by defining a current level and a voltage level for a data signal. The coded sequence is then transferred on the transfer path synchronously with a clock signal and is decoded in a second multiplexer/demultiplexer by evaluation of the received current level and of the received voltage level. From this, the transferred data sequence is determined.
