近年来，闪存以其非易失性、访问速度快、抗冲击、低功耗等优点在嵌入式应用中得到了广泛的应用。然而，由于其硬件特性，特别是其“写入前擦除”功能，它需要一个被称为FTL(闪存转换层)的软件层。本文综述了闪存FTL软件的发展现状。它定义了问题，提出了解决问题的算法，并讨论了相关的研究问题。此外，本文还给出了基于我们实现的每种FTL算法的性能结果。(C)2009爱思唯尔B.V.保留所有权利。
Recently, flash memory is widely adopted in embedded applications as it has several strong points, including its non-volatility, fast access speed, shock resistance, and low power consumption. However, due to its hardware characteristics, specifically its "erase-before-write" feature, it requires a software layer known as FTL (Flash Translation Layer). This paper surveys the state-of-the-art FTL software for flash memory. It defines the problems, addresses algorithms to solve them, and discusses related research issues. In addition, the paper provides performance results based on our implementation of each FTL algorithm. (C) 2009 Elsevier B.V. All rights reserved.
