Abstract

See full text

A system and method for floorplanning a memory. A computing system includes a processing unit which generates memory access requests and a memory. The size of each memory line in the memory includes M bits. A memory macro block includes at least a primary array and a sidecar array. The primary array stores a first portion of a memory line and the sidecar array stores a second smaller portion of the memory line being accessed. The primary array and the sidecar array have different heights. The height of the sidecar array is based on a notch height in at least one corner of the memory macro block. The notch creates on-die space for s reserved area on the die. The notches result in cross-shaped, T-shaped, and/or L-shaped memory macro blocks.
