ABSTRACT:
There is disclosed a multi-application transponder circuit for a contactless electronic identification and/or access system including, in particular, a non-volatile memory (18) having a segmented programmable memory space for receiving data relating to a plurality of distinct applications, this memory space including (i) a first memory zone (A) segmented into several memory words each dedicated to storage of data relating to a determined application from among said plurality of distinct applications, (ii) a second memory zone (B), called a shared zone, segmented into several memory words each able to be allocated to storage of data relating to any application from among said plurality of distinct applications, and (iii) a third memory zone (C) containing indications relating to the allocation of memory words of said second memory zone, at least, and for determining which memory word or words of said second memory zone are allocated to storage of data relating to a given application from among said plurality of distinct applications. There is also disclosed a memory management method for such a transponder circuit.
