Abstract

The present invention concerns a multi-frequency transponder (1) for communicating at a first frequency according to a first communication protocol and at a second frequency according to a second communication protocol, the second frequency being different from the first frequency. The transponder comprises a first physical memory (17) with a first memory structure for storing a first set of data of the first communication protocol; a second physical memory (19) with a second memory structure for storing a second set of data, different from the first set of data, of the second communication protocol; and a logic unit (7) for accessing the first and second physical memories (17, 19), the logic unit comprising a first control unit (9) for handling communications according to the first protocol, and a second control unit (11) for handling communications according to the second protocol. The transponder further comprises a mapping memory configured to store a logical memory map of at least one of the first and second physical memories (17, 19), the logical memory map comprising mapping information for the first or second control unit (9, 11) to access data items in both the first and second physical memories (17, 19).
