Matrix 3D memory is World's Smallest
nokiator writes "Most of the headlines about cool new high density memory technology are from DRAM or Flash manufacturers these days. Matrix Semiconductor, a small Silicon Valley start-up, broke the trend today and announced that the world's smallest 1-Gbit memory chip. Matrix's chip is an antifuse-based one-time programmable ROM. The total die area of the 1Gb chip is 31 square millimeters (smaller than the blue/red pills in the Matrix movie). Matrix claims that they can achieve this density through a proprietary 3D circuit technology that combines 150nm and 130nm process geometries. When Matrix moves to 90nm process technology, it should be possible to manufacture a 8Gb memory chip on a reasonable sized (i.e. cheap) die. There are many potential applications of this kind of low cost, very high density ROM technology, mostly in content distribution area. One 8Gb ROM chip would have sufficient storage capacity to store the contents of an entire movie using H.264 encoding."
ROMs can be very cheap. If they get to 8Gbit and then put it in a multichip stack to get to 4 or 8 GByte capacities, it could possibly give the movies on DVD industry a run for its money. The bad side of that is that we've been benefiting heavily from the demand that that industry has created is responsible for providing cheap RO and later WO and RW DVD drives for our PCs. The movie industry would love this format because the WO and RW versions would always be way more expensive than the RO version. The cost equation of copying would change dramatically.
