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.
Claims16
A data transfer method, which comprises the following method steps:
- coding a data sequence containing at least two bits by defining a current level and a voltage level for a data signal;
- transferring the data signal;
- and
- decoding the data signal by evaluating the current level and the voltage level and determining therefrom the data sequence containing the at least two bits transferred in the data signal.
A data transfer method, which comprises the following method steps:
- coding a data sequence by defining a current level and a voltage level for a data signal and multiplexing the current level from at least two current intensities and multiplexing the voltage level from at least two voltage levels;
- transferring the data signal;
- and
- decoding the data signal by evaluating the current level and the voltage level and determining therefrom the data sequence transferred in the data signal.
