Abstract: A memory system includes a management-information restoring unit. The management-information restoring unit determines whether a short break has occurred referring to a pre-log or a post-log in a NAND memory. The management-information restoring unit determines that a short break has occurred when the pre-log or the post-log is present in the NAND memory. In that case, the management-information restoring unit determines timing of occurrence of the short break, and, after selecting a pre-log or a post-log used for restoration, performs restoration of the management information reflecting these logs on a snapshot. Thereafter, the management-information restoring unit applies recovery processing to all write-once blocks in the NAND memory, takes the snapshot again, and opens the snapshot and the logs in the past.

Abstract: A game piece for a fighting game is movable on a surface when an external force is applied to the game piece, and includes a mount, and a figurative body provided on the mount and having an attack unit for overturning a game piece of an opponent. The mount includes a front portion that protrudes to the front with respect to a support position on the mount for the figurative body, a front side portion that protrudes to at least one of the left and right from the front portion, and side portions, at least a portion of one of the side portions provided with the protruding front side portion being located at a position close to the support position with respect to a protruding end of the front side portion.
