Abstract

This paper reviews Flash memory technology and flash translation layer (FTL) that provides a block device interface out of flash memory. It also describes two implementations of FTL that represent two extreme points in the spectrum of cost-performance trade-offs in FTL implementation. After presenting results on the performance and energy- efficiency of the two FTLs, this paper argues for a configurable FTL to address the diversity of mobile embedded systems in terms of cost and performance requirements.
