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 6):
The memory system according to  claim 1 ,\n wherein the internal code in-error bit estimation unit includes\n a data input unit that receives the first result of decoding which is obtained by the bounded distance decoding that is performed by the first external code decoder on the reception word, as an input, \n a first error level calculation unit that calculates an error level indicating the degree of likelihood to which each of the estimated in-error bits is in error, and records a sequence of the calculated error levels, and \n an in-error-bit estimation unit that estimates the in-error bit from the bit sequence that is the first result of decoding which is received by the data input unit, using the rule for the internal code, and retains a bit sequence of the estimated in-error bits.
