Abstract: A register file includes a substrate, a plurality of entries, and a plurality of read ports. Each entry includes a corresponding subset of a plurality of memory cells defined on the substrate. Each read port includes a plurality of access elements defined on the substrate. Each access element is associated with a particular common bit position of each of the entries. A plurality of entry access groups are disposed in adjacent columns on the substrate. Each entry access group is associated with a corresponding one of the plurality of entries and includes the access elements for all of the read ports for the corresponding entry.
