With burst 2, you get or put 2 data words per read or write command. With burst 4, you get or put 4. Burst 4 is usually capable of running a little faster than burst 2 as far as frequency of operation. In some applications you might be able to use either part. In others you might want the quicker random access of the burst 2.
