A memory with at least two banks, each bank capable of storing N=2n unique lines of data, each line of data addressable by an n-bit code corresponding to an address index i, 0</=i</=N-1, provides for operation in either an OR-line or split-line mode. In the OR-line mode, data from line i, corresponding to index i, is available from all banks. In the split-line mode, data is available from line address i of one set of banks, and address i+1 from another set of banks. In either mode, wrap-around from line address i=N-1 to i=0 is provided by the use of an additional line of memory located at a position corresponding to i=N that contains the same data as the line corresponding to i=0. In this manner, a complete wrap-around read capability is provided without suffering a memory speed loss.
