摘要： A nonvolatile storage system has multiple nonvolatile storage media and a controller coupled to the multiple nonvolatile storage media. The controller has a storage area for storing management information including probability management information denoting error probability information of a unit physical area in a nonvolatile storage medium, and an error correcting circuit for carrying out coding and decoding by a low density parity check code. An error probability is a probability that data within the unit physical area is incorrect, and is a prior probability, which is the probability of prior to this data having been read. The controller, in a data read process, identifies based on management information an error probability, which is the error probability of a unit physical area including the physical area of the read source and is better suited to the state of the read source in the current read process than the error probability identified for the same unit physical area in a past read process, and uses the identified error probability to correct the read data using the error correcting circuit.

摘要： To eliminate duplicated caching in a storage system with plural disk cache partitions, which are obtained by dividing a disk cache. A storage system includes non-volatile medium that stores data; a disk cache that temporarily stores data to be stored in the non-volatile medium; a control unit that controls input and output of data to and from the non-volatile medium; and a memory unit that stores information used by the control unit. The control unit divides the disk cache into at least one of independent disk cache partitions. The memory unit stores the first information that describes states of respective memory areas in the disk cache, and the second information that indicates states of respective memory areas in the disk cache used by the divided disk cache partitions. The second information includes information that identifies the first information corresponding to the respective memory areas in the disk cache.
