PROBLEM TO BE SOLVED: To prevent further deterioration in reliability of a nonvolatile storage device by constructing a system so as not to perform a writing operation to the nonvolatile storage device when the service life of the nonvolatile storage device gets closer to termination, and prevent data corruption of the nonvolatile storage device.SOLUTION: An information recording system comprises: a semiconductor storage device 2 which includes a nonvolatile semiconductor memory, a volatile semiconductor memory, a controller circuit, a temperature sensor and an interface circuit; and a host device 1 which transmits writing and reading commands. The nonvolatile semiconductor memory and the volatile semiconductor memory are configured to be able to record the first information designating the physical address corresponding to the logical address. The nonvolatile semiconductor memory is configured to store the second information, third information, fourth information, fifth information, sixth information and seventh information. The host device is configured to be able to display information based on the second or third information, information based on the fourth or fifth information and information based on the seventh information on a display device.SELECTED DRAWING: Figure 1 |
