Abstract

See full text

A computer has a pageable memory which comprises a plurality of memory units each made up of a plurality of blocks of addressable memory locations. A designated one of the blocks is required to be accessed in combination with the remainder of the blocks. Logic circuits are responsive to first and second groups of address bits to generate signals which enable a selected one of the memory units and access a selected one of the blocks on the selected unit. The designated block is accessed directly by one of the aforesaid groups of address bits.
