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.
