Abstract: In the field of data reading and writing technologies, a data writing method is associated with a data writing apparatus and an electronic device. The data writing method includes: determining whether a start storage address of a first data block is aligned with a bus bit width of a storage; in response to that the start storage address of the first data block is not aligned with the bus bit width of the storage, determining whether a second data block which is a data block immediately before the first data block is compressed; in response to that the second data block is compressed, executing complete writing on a first beat of the first data block.
