Abstract: A system design support apparatus identifies design information elements each achieving a corresponding one of multiple requirements concerning a system to be newly designed, by using a first table. When multiple design information elements are identified with respect to a certain one of the requirements as a result of the identification, the system design support apparatus identifies a design information element that establishes a combination at a higher aptitude rank among the multiple design information elements, while referring to an aptitude rank of combined use of each of the multiple design information elements and design information elements identified with respect to another requirement among the multiple requirements, by using a second table. Then, the system design support apparatus outputs the design information elements, which are identified with respect to the multiple requirements, to a predetermined device.

Abstract: In a nonvolatile memory, the threshold is restored to a state before changing, without increasing number of writing undesirably. In a system including a nonvolatile memory, a random number generator, and a controller accessible to the nonvolatile memory, every time access to the nonvolatile memory is performed, the controller determines a refresh-targeted area, based on a random number generated by the random number generator. The controller is made to perform refresh control to re-write to the refresh-targeted area. By such refresh control, the threshold is restored to a state before changing, without increasing the number of writing undesirably.
