Magnetoresistive random access memory (MRAM) promises computers that turn on instantly, smarter gadgets, and a revolution in chip design--if it can elbow its way into the market. The first commercial prototype chips should hit the market within 2 years. But it isn't certain that MRAM can topple the reigning champion of computer memory, an electronic technology called dynamic random access memory, because DRAM has a huge head start and is inexpensive.
