Electic Tech schrijft dat Motorola als eerste succesvol een 256Kb MRAM chip heeft gedemonstreerd. MRAM heeft als voordelen boven het huidige DRAM en flash geheugen dat het goedkoper en sneller moet worden. Daarnaast moet het ook nog eens gegevens kunnen bewaren als er geen spanning op staat. Koppel dit met een laag energie verbruik en je snapt waarom veel geheugenbakkers veel zien in deze technologie. Motorola is van plan om in 2003 de eerste MRAM samples te leveren en in 2004 moet de massaproductie starten:
Motorola Labs, the research arm of Motorola, Inc. (NYSE: MOT), partnering with the DigitalDNA™ Laboratories of the Semiconductor Products Sector, today at the IEEE International Solid State Circuits Conference, disclosed an industry milestone in developing MRAM (magnetoresistive random access memory). This universal memory has the potential to revolutionize the $48 billion semiconductor memory market and offers an array of innovative, affordable memory-based applications for digital consumers worldwide.
"We believe Motorola is ready to lead the industry, as the first company to demonstrate and successfully process 256k MRAM chips," said Padmasree Warrior, corporate vice president and chief technology officer, Motorola's Semiconductor Products Sector.
[...] The memory successfully demonstrated by Motorola is a 256kb nonvolatile MRAM based on a memory cell defined by a single transistor (1T) and a single Magnetic Tunnel Junction (MTJ) with read and write cycles of less than 50ns. The memory organization is 16k x 16, and the measured read power consumption is 24mW at 3 volts. This structure provides an extremely cost competitive memory. The fast read and write speed combined with virtually unlimited read and write cycles and competitive cost could enable MRAM to replace existing memory technologies including Flash, DRAM, and all but the fastest SRAM.
