A deinterleaving device includes a memory space, the memory space being divided into a plurality of N segments with different lengths respectively. A method of accessing data in a deinterleaving device, the method including performing the following steps during a first time cycle: reading first read data from a first address of a first segment; reading second read data from a first address of a second segment, and writing first write data into the first address of the second segment; reading third read data from a first address of a third segment, and writing second write data into the first address of the third segment; repeating the above reading and writing steps until reading Nread data from a first address of an Nsegment, and writing N&#x2212;1write data into the first address of the Nsegment; writing Nwrite data into the first address of the first segment.
