Categorization of Multilevel-Cell Storage-Class Memory: An RRAM Example

This paper provides new insights into the effect of device characteristics on multilevel-cell (MLC) operation, aiming at potential benefits, such as the reduction of write latency and peripheral circuit design overhead. A general categorization of the MLC-operating schemes in storage-class memory (SCM) is proposed to connect the total number of write inputs with fundamental device properties. The ...
