Integrated Process Monitoring Enables New Memories
(World News USA)

The Internet of Things (IoT), Big Data and Artificial Intelligence (AI) are driving the need for higher speeds and more power-efficient computing. The industry is responding by bringing new memory technologies to the marketplace. Three new types of memory in particular-MRAM (magnetic random access memory), PCRAM (phase change RAM) and ReRAM (resistive RAM)-are emerging as leading candidates for use in IoT and cloud environments. All three of these emerging memories are based on delicate new materials that require breakthroughs in process technology and high-volume manufacturing. The critical films are so thin and variation-sensitive that metrology is crucial. The sensitivity of the...
