摘要： A management information generating method wherein logical and physical block addresses (BAs) of continuous addresses are associated with each other in the BA translation table. When a logical block is constructed, a value is set for a maximum number of allowable defective physical blocks. A logical block having fewer defects than the set number is set usable, and a logical block having more defects than the set number is set unusable. System logical block construction is performed to preferentially select physical blocks from a plane list including a large number of usable blocks to equalize the number of usable blocks in each plane list. It is determined whether the number of free blocks is insufficient on the basis of a first management unit and whether the storage area for the indicated capacity can be reserved on the basis of the management unit different from the first unit.

摘要： According to one embodiment, a storage device includes, when power is supplied to a storage unit, counting of an elapsed time is started. If a command is input from a host device, and the elapsed time from input of a previous command to input of a current command is calculated based on time information clocked by the host device and on a counter value counted until the corresponding command is input. Matching of the time information is determined based on a temporal relation between the adding result of adding the calculated elapsed time to the time information included in the previous command and the time information included in the current command. When the mismatching is determined, data in the storage unit is invalidated.

摘要： According to one embodiment, a memory system includes a data manager and a data restorer. The data manager multiplexes difference logs by a parallel writing operation and stores them in a second storage area, the difference logs being difference logs indicating difference information before and after update of a management table; and thereafter multiplexes predetermined data as finalizing logs and stores them in the second storage area. The data restorer determines a system status at startup of the memory system, by judging whether irregular power-off occurs or data destruction occurs in the second storage area, based on a data storage state of the difference logs and the finalizing logs stored in the second storage area.
