Abstract
The invention relates to a receiving unit for performing a calibration of a reference voltage, comprising a reference voltage unit for generating and applying a reference voltage on the evaluation unit depending on a converter value, an evaluation unit for receiving a single-ended data signal and being configured to determine an evaluation signal based on the data signal and the reference voltage, and a logic unit configured to perform a calibration process for calibrating the reference voltage. The logic unit is configured to command a memory device to apply a permanent digital logical state on a data line, to iteratively adapt a converter voltage to substantially match the voltage level of the logical state on the data line, and to determine the reference voltage depending on the converter voltage for which the voltage level of the logical state on the data line has been substantially matched.
