Abstract
There are provided an error correction circuit and a method of operating the same. The circuit may performs error correction decoding within a maximum global iteration number G, and may include a mapper configured to generate read values quantized into g+1 levels to be used in a g-th global iteration by using read values corresponding to g number of read voltages, a node processing component configured to perform error correction decoding, during the g-th global iteration, by using the read values quantized into g+1 levels, a syndrome information management component configured to manage syndrome information corresponding to the g-th global iteration, and a global iteration control component configured to, when error correction decoding fails in the g-th global iteration, determine whether the syndrome information corresponding to the g-th global iteration satisfies a condition defined in a global iteration skip policy, and decide whether to skip (g+1)th to (G−1)th global iterations.
