Abstract:
Disclosed is a memory card (103, 203), a device (102) and methods for maintaining and utilizing a bridge data bus (224) between the two interfaces (220, 222) of a combo-SIM or equivalent chip card (103, 203). The memory card (103, 203) includes first (216) and second data buses (218) operatively coupled to the external interface (212), the second data bus (218) having faster data transfer capability than the first data bus (216). The memory card (103, 203) includes a subscriber identity block (209) and a mass storage block (215). The subscriber identity block (209) is coupled to the external interface (212) via the first data bus (216), and is effective to store subscriber identity information. The mass storage block (215) is coupled to the external interface (212) via the second data bus (218). The memory card (103, 203) includes a third data bus (224) coupled between the subscriber identity block (209) and the mass storage block (215), the third data (224) bus having faster data transfer capability than the first data bus (216).
