Abstract: A data encoding method, an electronic device, and a storage medium are disclosed. The data encoding method may include: writing information bits into at least two cache blocks, where the cache blocks store parity bits corresponding to the information bits, and two adjacent bits of data of the parity bits are stored in different cache blocks; and performing low density parity check code (LDPC) encoding according to the information bits and the parity bits in the cache blocks.
