Abstract (en)

[origin: WO2005055052A2] The invention relates to a smart card chip provided with a non-volatile system memory (ROM, Flash1), a virtual java card machine implemented in the non-volatile system memory (ROM, Flash1), a non-volatile application memory (EEPROM, Flash2), a volatile working memory (RAM) and a variable memory area reserved for global variables. The variable memory area is reserved in the volatile working memory (RAM). Preferably, the variable memory area is statically reserved. The use of variables can be limited to system packages and, optionally, to preloaded (ROM/EEPROM) packages.
