Magnetic RAM is inching forward, bringing the benefits of nonvolatility with the performance of RAM. Motorola's Semiconductor Product Sector (http://e-www.motorola.com) is sampling 4-Mbit magnetoresistive RAM chips made on its 0.18-micron lines, quadrupling the storage capacity over parts introduced in mid-2002. Honeywell International (www.ssec.honeywell.com) is licensing Motorola's process technology, planning to make radiation-hardened chips for military applications. Honeywell will merge the technology with its silicon-on-insulator IC technology.
