The technology, called Trinity, offers a significant advantage against one-gigabit flash memory chips from makers like Intel, AMD and Infineon, which have on average three times as much surface area.
Matrix was founded in 1998 to exploit the third dimension in chip design. It announced last November that it had begun volume manufacturing of an initial generation of its technology - also in four layers, like a layer cake, with each layer storing millions of 1's and 0's. It currently ships more than one million chips a month.
While all computer chips are now composed of many layers of materials, Matrix has been the most aggressive in effectively creating semiconductor chips that have distinct levels, like separate floors in a building.
