    Abstract: A polar code encoding and decoding method includes generating a first and second sub-codewords. The sub-codewords correspond to pre-codewords, and the pre-codewords have a shared data aspect. The sub-codewords provide useful error-recovery for data stored in a memory. When data is read from the memory, decoding takes place. The data read operation may include hard decision decoding, soft decision decoding, or hard decision decoding followed by soft decision decoding. In the method, the shared data aspect is used to decode a first sub-codeword for which decoding was not initially successful. An apparatus is also provided.

    Abstract: A memory system includes a nonvolatile memory device having a plurality of physical sectors, a mapping table, and a memory controller including a plurality of hash functions. The memory controller is configured to access the physical sectors using the mapping table and the hash functions. The memory controller is configured to receive a sequence of logical block addresses (LBAs) from a host and logical sector data for each of the LBAs, generate a first virtual address by operating a selected hash function among the hash functions on a first logical block address (LBA) among the sequence, compress the logical sector data to generate compressed data, and store the compressed data in a first physical sector among the physical sectors that is associated with the first virtual address.

    Abstract: A memory device controller includes an error correction processor and a compression processor. The error correction processor is configured to obtain error location information for page data received from a source memory block over a memory channel. The compression processor is configured to compress the obtained error location information, and to output the compressed error location information to a target memory block without the page data over the same memory channel.
