MULTIMODE ACCESSIBLE STORAGE FACILITY

A multimode accessible storage facility (10) is described that allows block access in a block access mode and row access in a row access mode. The facility comprises-a memory unit (20) comprising a plurality of memory banks (20.0, . . . , 20.F) each having a respective bank index (0, . . . , F), -an address generator (30) for generating for each of said memory banks a rotated bank address as a function of an input address and a shift parameter, -an input vector data rotator (40) for rotating an input vector and for providing vector elements of the rotated input vector to a respective bank of the memory unit, and -an output vector rotator (50) for inverse rotating a vector comprising vector elements retrieved from respective banks of the memory unit and for providing the rotated output vector.
