Abstract
According to one embodiment, a data recovery circuit includes an XOR operation unit, an erroneous bit position inferring unit, an error factor inferring unit, and an error provisionally determining unit. The XOR operation unit performs a bitwise XOR operation on M data sequences of N bits, where M and N are integers of two or greater. The erroneous bit position inferring unit infers an erroneous bit position based on the XOR operation result. The error factor inferring unit infers the inverted direction of the erroneous bit. The error provisionally determining unit performs bit inversion in the erroneous bit position, the direction of the bit inversion being opposite to the inferred inverted direction.
