Abstract
A low density parity check (LDPC) decoding device includes a data generator for generating information with a first precision; a data converter for converting the information into a message with a second precision greater than the first precision; and a decoding processor for performing a low density parity check (LDPC) decoding using the message to generate decoded data.
Claims18
A decoding device comprising:
- a data generator suitable for generating information comprised of a first number of bits representing a first precision;
- a data converter suitable for converting the information into a message comprised of a second number of bits representing a second precision greater than the first precision;
- and
- a decoding processor suitable for performing a low density parity check (LDPC) decoding using the message to generate decoded data.
A memory system comprising:
- a memory device;
- and
- a memory controller suitable for controlling the memory device to perform a read operation,
- wherein the memory controller includes a decoding device including:
- a data generator suitable for receiving data read from the memory device and generating soft decision data for the read data, the soft decision data comprised of a first number of bits representing a first precision;
- a data converter suitable for converting the soft decision data into a message comprised of a second number of bits representing a second precision greater than the first precision;
- and
- a decoding processor suitable for performing a low density probability check (LDPC) decoding using the message to generate decoded data.
A method for operating a memory system including a memory device and a memory controller suitable for controlling the memory device to perform a read operation, the method comprising:
- receiving data read from the memory device;
- generating soft decision data for the read data, the soft decision data comprised of a first number of bits representing a first precision;
- converting the soft decision data into a message comprised of a second number of bits representing a second precision greater than the first precision;
- and
- performing a low density probability check (LDPC) decoding using the message to generate decoded data.
