Abstract
According to one embodiment, a memory system includes a nonvolatile memory, an encoding part configured to generate a plurality of component codes including a first component code and a second component code different from the first component code, by using, as an information symbol, at least one symbol of a plurality of symbols included in user data to be written into the nonvolatile memory, and a memory interface configured to write the plurality of component codes into the nonvolatile memory. The encoding part includes a plurality of encoders each configured to generate a parity corresponding to each of the plurality of component codes, and a first distributor configured to divide a first symbol string of the user data into a plurality of chunks, each of which has a first symbol length smaller than that of the first symbol string, and to input each of the plurality of chunks generated by the division, into any one of at least different two of the plurality of encoders. The memory interface is configured to write the first symbol string and parities corresponding to the first symbol string into the nonvolatile memory.
