摘要：
The invention concerns a chip card (21) comprising data processing means and main data storage means, wherein the processing means include: means for detecting, while the chip card is operating, that the main storage means contain an amount of data such that an operation cannot be executed; means for selecting, in the main storage means, a set of data to be unloaded (K), whereof the unloading can release in the main storage means a space sufficient for executing said operation; means for unloading the set of data to be unloaded (K) into secondary storage means (23 to 25), in the event said secondary storage means do not contain said data set to be unloaded. The invention also concerns the associated communication method and protocol.
