摘要： A method for channel-coding information bits using a code generation matrix including 32 rows and A columns corresponding to length of the information bits includes, channel-coding the information bits having “A” length using basis sequences having 32-bit length corresponding to columns of the code generation matrix, and outputting the channel-coded result as an output sequence. If “A” is higher than 10, the code generation matrix is generated when (A-10) additional basis sequences were added as column-directional sequences to a first or second matrix. The first matrix is a TFCI code generation matrix composed of 32 rows and 10 columns used for TFCI coding. The second matrix is made when at least one of an inter-row location or an inter-column location of the first matrix was changed. The additional basis sequences satisfy a value 10 of a minimum Hamming distance.

摘要： Memory systems and operating methods thereof comprise a memory storage and an error control coding (ECC) unit. The memory storage stores data which is split into a plurality of data chunks. The error control coding (ECC) unit is suitable for arranging each data chunk into codewords, each data chunk is arranged as part of at least two codewords, and mapping the codewords by reverse indexing the data chunks.

摘要： The present disclosure includes apparatuses and methods for ECC operation associated with memory. One example apparatus comprises a controller configured to perform an error correction code (ECC) operation on a codeword stored in the memory, wherein the codeword includes a first number of ECC bits and the first number of ECC bits are generated based on an encoding matrix, wherein each row of the encoding matrix has an odd number of bits having a binary value of 1.

摘要： A method of encoding user data into codevectors of an error correcting code, includes generating a first block of data symbols including user data symbols and dummy data symbols; encoding the first block using an ECC encoder to obtain a codeword comprising the first block of data symbols and a second block of parity symbols; and generating a codevector by selecting a user data portion of the user data symbols from the first block and a parity portion of the parity symbols from the second block. The sum of a number of the user data portion and a number of the parity portion is smaller than the sum of a number of the user data symbols and a number of the parity symbols of the second block.
