Abstract
A semiconductor storage device, a method of controlling the same, and an error correction system allow reduction in power consumption and circuit scale without detriment to error correction capability. An error correction code (ECC) circuit of a solid state drive (SSD) performs first error correction on read data using a first error correction code (Hamming code), and further performs second error correction on the result of the first error correction using a second error correction code (BHC code). Furthermore, the ECC circuit performs third error correction on the result of the second error correction using a third error correction code (RS code).
