ABSTRACT:
A method and an apparatus for transmitting data on an internal and/or external transfer path in and/or to a semiconductor component such as a semiconductor memory, in which, a first coder/decoder codes a data sequence by stipulating a signal level of a data signal that is transmitted on a transfer path in sync with a clock signal. A second coder/decoder decodes the transmitted data signal by assessing the signal level in order to ascertain the original data sequence. In addition to the coded data signal, a reference signal block having at least one reference signal level is transmitted. The reference signal level is compared with the signal level of the transmitted coded data signal in the second coder/decoder in order to assess the signal level.
