A Smart Hybrid Solid-State-Drive Storage System based on Nonvolatile Storage-Class-Memories : Device, Circuit Design and Architecture

Abstract

Recently, there are many kinds of non-volatile memories like NAND flash, MRAM, PCM and ReRAM. Since there is no perfect non-volatile memories, a co-design of device, circuits and systems is essential in order to achieve high performance and reliability with low cost and power consumption. To reach this goal, this paper proposes a hybrid solid-state drive based storage system with optimum circuits to manage each non-volatile memory characteristics.
