ABSTRACT:
An integrated memory cube structure and method of fabrication wherein stacked semiconductor memory chips are integrated by a controlling logic chip such that a more powerful memory architecture is defined with the functional appearance of a single, higher level memory chip. A memory/logic cube is formed having N memory chips and 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 chips such that a single memory chip architecture with N.times.M memory devices appears at the cube's I/O pins. A corresponding fabrication technique includes an approach for facilitating metallization patterning on the side surface of the memory subunit.
