Abstract: The present disclosure relates to technical field of data access, and discloses a matrix storage method, a matrix access method, an apparatus and an electronic device in the technical field of data access. The matrix storage method includes: dividing a matrix into a plurality of data blocks with a preset segmentation granularity of N rows×M columns; the plurality of data blocks includes at least one first data block of N rows×M columns; if the column number of the matrix is not an integer multiple of M, the plurality of data blocks further includes at least one second data block of N rows×P columns, the second data block is aligned with an adjacent row of first data block; and storing the data in each of the first data blocks and the second data blocks continuously in an off-chip storage.
