| description | A memory IC card including a card substrate, a semiconductor device mounted on the card substrate, which includes an CPU, a flash memory, a memory block and a flash memory rewrite circuit having a rewrite data control circuit that receives a rewrite instruction of the flash memory from the CPU to store data for a designated byte of a page for rewriting to the memory block, a page data control circuit that sends data of the page excepting the designated byte in the flash memory to the memory block to prepare new page data in the memory block and a data set control circuit that writes the new page data prepared in the memory block to the flash memory; outer terminals mounted on the card substrate ; wirings provided on the card substrate to connect the outer terminals. |
