摘要： A method and system for decoding information read from a non-volatile memory uses a two stage decoding algorithm, where the first stage is a high-speed, low precision decoder and the second stage is a low-speed, high precision decoder. Most of the time only the first stage of the decoder is used, which lowers the average power consumption of the decoding process.
