According to one embodiment, a memory system includes a first memory, an interface circuit, and a processor. The interface circuit is configured to receive a first request from an external device. The processor is configured to select a mode among a plurality of modes in response to the first request, and perform, on data read from the first memory, error correction of the selected mode.

Memory system

A memory system according to an embodiment includes a non-volatile memory and a controller configured to control the non-volatile memory. The controller includes an interface and a control unit. The interface receives, from a host, a first instruction to change a performance of the memory system as a performance control instruction. The control unit controls the memory system on the basis of the performance control instruction such that the number of parallel operations of parallel operating units which are operated in parallel in the memory system is changed.

According to one embodiment, a controller includes a quality measuring unit, a block classifying unit, and a multi-plane setting unit. The quality measuring unit measures quality of a block. The block classifying unit classifies the block for every plane based on a measurement result of the quality. The multi-plane setting unit selects one block belonging to the same classification from each plane and combines the blocks to generate the multi-plane.

Memory system and method of controlling memory system

According to one embodiment, an information recording apparatus includes a divider, a generator, and a recorder. The divider is configured to divide recording data into a plurality of recording data blocks for each predetermined recording unit. The generator is configured to set, as a first block set, n recording data blocks recorded in corresponding areas in file system management areas of n, first to nth (n: integer, n&#x2267;2) storages, and generate first parity data from the n recording data blocks forming the first block set. The recorder is configured to record the n recording data blocks forming the first block set and the first parity data.
