Abstract:
A memory system includes a nonvolatile memory and a memory controller configured to perform reading of a concatenation code from the nonvolatile memory in response to an external command, the memory controller including a decoder circuit which decodes a reception word in the concatenation code. The decoder circuit includes a first external code decoder that performs decoding on an external code portion, an internal code in-error bit estimation unit that performs estimation of an in-error bit on a bit sequence from the first external code decoder, based on a rule for an internal code in the concatenation code, and outputs a set of in-error bits that is obtained by the estimation, and a second external code decoder that performs decoding which uses the set of in-error bits that is output from the internal code in-error bit estimation unit, on the bit sequence from the first external code decoder.

Claim (Index 10):
The memory system according to  claim 8 , further comprising:\n a third parity inspection unit that performs parity inspection of the external code on the one or more test patterns, wherein the second error level calculation unit calculates the sum of the error levels at the position at which the bit inversion occurs, for one or more decoded word candidates each of which has a syndrome value of 0, as a result of the parity inspection by the third parity inspection unit, with the reception word being set to be the reference.
