摘要：An integrated memory cube structure and method of fabrication whereinstacked semiconductor memory chips are integrated by a controlling logic chip such thata more powerful memory architecture is defined with the functional appearance of asingle, higher level memory chip. A memory/logic cube is formed having N memory chipsand at least one logic chip, with each memory chip of the cube having M memory devices.The controlling logic chip coordinates external communication with the N memory chipssuch that a single memory chip architecture with N×M memory devices appears at thecube's I/O pins. A corresponding fabrication technique includes an approach forfacilitating metallization patterning on the side surface of the memory subunit.
