Chances and challenges of emerging memories for DRAM application

The interests in various emerging memories are rapidly increasing. Among the emerging memories, only STT-RAM and ZRAM show the similar performance to DRAM, in terms of write endurance and write speed. They should be potential candidates for DRAM application, since many outstanding results have been demonstrated recently in spite of the fairly new technology. Nevertheless, the technical maturity and cost effectiveness of the emerging technologies should require the further research and development.
