Abstract
An information processing device of an embodiment has an input unit, a storage unit, a read control unit, and a write control unit. A read request and a write request are input to the input unit. The storage unit stores management information. When the read request is input, the read control unit reads read data including the management information from the storage unit, references the management information, and outputs only non-zero data included in a predetermined range of a block row. The write control unit writes only non-zero data to the storage unit and updates the management information immediately before a start position of the continuous non-zero data started from a largest position in the continuous non-zero data started from a position smaller than the predetermined range, a last management information stored in the predetermined range, and the last management information in the predetermined range.
