Flashpower: A Detailed Power Model for Nand Flash Memory

Free registration required

Executive Summary

Flash memory is widely used in consumer electronics products, such as cell-phones and music players, and is increasingly displacing hard disk drives as the primary storage device in laptops, desktops, and even servers. There is a rich micro architectural design space for flash memory and there are several architectural options for incorporating flash into the memory hierarchy. Exploring this design space requires detailed insights into the power characteristics of flash memory. In this paper, the authors present FlashPower, a detailed analytical power model for Single-Level Cell (SLC) based NAND flash memory, which is used in high-performance flash products. They have integrated FlashPower with CACTI 5.3, which is widely used in the architecture community for studying memory organizations.
