PURPOSE: An information processing system, a longevity evaluation method, and a recording medium are provided to evaluate the longevities of DRAMs before errors caused by data inconsistency occur on computer systems and notify administrators of the computer systems.;CONSTITUTION: A longevity evaluation device(1) is an information processing system including a memory module(14) which functions as a primary storage and a CPU(13) which functions as a central arithmetic unit. The memory module includes a DRAM(141) and an SPD(Serial Presence Detect) ROM(142). The CPU properly reads and performs programs, such as the BIOS, the OS, and the longevity evaluation program from a BIOS ROM(19) or a storage section(10) and processes information input from a USB/PCI interface(18), a control section, and the like, and information read from the storage section. Thereby, the CPU also functions as a timer section, a read control section, a longevity evaluation section, a warning section, a refresh instruction section, and a write section. The CPU as the timer section measures the elapsed time after data is entered into the memory module. The CPU as the read control section sends a read command as well as an address to be accessed to the memory module and reads data from the address in the memory module. The CPU as the longevity evaluation section evaluates the longevity of the memory module based on existence of an error in the read data and the elapsed time. The CPU as the warning section outputs a warning message to a predetermined output destination when the end of the longevity is approaching or when the end of the longevity has been reached. The CPU as the refresh instruction section periodically sends a refresh instruction to the memory module to perform a refresh operation. The CPU as the write section sends a write command as well as data to the memory module to write the data.;COPYRIGHT KIPO 2010
