Abstract

For the validation of memory chips, especially for use in portable data-carrier arrangements of data exchange systems, a change-over can be made between the data-exchange mode and the checking mode, in particular the signal transit time of the checking data through a processing circuit serving as a validation feature. <IMAGE>
