摘要: A flash memory includes a data area in which first and second k-bit data (k is a natural number) are stored; and an additional data area in which a first additional m-bit data (m is a natural number) and a second additional m-bit data used to respectively identify the first and second data are stored. The first additional data and the second additional data have different values.

摘要: 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.

摘要: PROBLEM TO BE SOLVED: To return a threshold to a state before fluctuation without undesirably increasing writing frequencies in a nonvolatile memory. SOLUTION: A system includes: a nonvolatile memory (14); a random number generator (12); and a controller (11) capable of accessing the nonvolatile memory, and determines an area for refreshment with the controller based on random numbers generated by the random number generator whenever the nonvolatile memory is accessed. Then, the controller is made to execute refreshment control for performing rewrite to the area for refreshment. By such refreshment control, the threshold is returned to the state before fluctuation without undesirably increasing writing frequencies. COPYRIGHT: (C)2010,JPO&INPIT
