A fast translation mechanism converts the absolute addresses provided to a memory unit to corresponding physical addresses useable by the memory unit, which is comprised of cards of non-uniform size. Non- identical groups of cards provide the bit width dimension to the memory unit, with one card from each group accessed at the same time from the same absolute address. The total addressable size of each group is the same. In a memory unit, where the data spans multiple cards and groups, the address for an access results in the selection of one card within each group, as well as the correct memory location within each card.
