ABSTRACT:
A data accessing system for interfacing between a smart card and a non-volatile memory is provided. The non-volatile memory has a smart card exclusive area accessible to a plurality of smart card applications. The smart card exclusive area includes a plurality of record unit sets respectively having a plurality of record units. The data accessing system has a buffer for temporarily storing data to be written into the smart card exclusive area and a data accessing protocol unit managing an access parameter table, a plurality of application information tables, and a plurality of record unit set link tables. The smart card applications access the smart card exclusive area in a unit of record unit set, and the size of a record unit set is a multiple of an access unit of the non-volatile memory. Accordingly, the number of accesses to the non-volatile memory is reduced and data security is increased
