NONVOLATILE MEMORY DEVICE AND RELATED READ METHOD USING HARD AND SOFT DECISION DECODING |
摘要 |
A storage device comprises a nonvolatile memory device comprising a plurality of memory cells, and an error correction circuit configured to receive primary data and secondary data from the nonvolatile memory device and to perform a hard decision decoding operation on the primary data and further configured to perform a soft decision decoding operation on the primary data based on the secondary data. The primary data is read from the plurality of memory cells in a hard decision read operation and the secondary data is read from memory cells programmed to a specific state from among the primary data. |
