ABSTRACT
Heterogeneously-integrated memory system is configured with various types of storage class memories (SCMs) and NAND flash memories. SCMs are faster than NAND flash, and they are divided into memory and storage types with their characteristics. NAND flash memories are also classified by the number of stored bits per memory cell. These non-volatile memories have trade-offs among access speed, capacity and bit cost. Therefore, mix and match of various non-volatile memories are essential to simultaneously achieve the best speed and cost of the storage. This paper proposes a design methodology with unique interaction of device, circuit and system to achieve the appropriate configurations in the heterogeneously-integrated memory system for application.
