Yole sees STT-MRAM as the most suitable technology to start replacing DRAM in 2018
Yole Developpement released a new emerging-memory market report in which they try to asses the future of the memory market. Yose says that Phase-change memory (PCM) is pretty much dead, and the two main emerging memory technologies are MRAM and Resistive random Access Memory (ReRAM or RRAM).
While RRAM is very promising in the near future, with support from Micron (they plan to release RRAM chips in 2015) and Panasonic while other players are expected to react quickly. RRAM and STT-MRAM will compete in 2015-2016 in some standalone markets (such as embedded MCU, wearables and smart cards and the storage class memory for enterprise storage which will be the biggest market), and it's not clear yet which technology will be the most popular.
