Flash (5) 썸네일형 리스트형 [펌] 리눅스 플래시 파일 시스템 분석 M. Tim Jones, 컨설턴트 엔지니어, Emulex Corp. 요약: JFFS(Journaling Flash File System)와 YAFFS(Yet Another Flash File System)에 대해 들어보았을테지만, 기반 플래시 디바이스 위에서 동작하는 파일 시스템이 무엇을 의미하는지 알고 있습니까? 이 기사는 리눅스(Linux®)를 위한 플래시 파일 시스템에 대해 소개하고, 닳기 균등화를 통해 반영구적인 기반 디바이스(플래시)를 보호하는 방법을 익히고, 기본적인 설계와 함께 다양한 플래시 파일 시스템을 알아보겠습니다. 원문 게재일: 2008 년 9 월 23 일 ------------------------------------------------------------------------.. Flash design specialist AboUnion taps SSD controller market Josephine Lien, Taipei; Jessie Shen, DIGITIMES [Friday 20 March 2009] Taiwan's AboUnion Technology, a memory IC design house specializing in NAND flash applications, is eyeing the market for solid-state drive (SSD) controllers, according to the company. The company has unveiled its 32-bit CPU SSD controller based on ARM platform designs. AboUnion on March 19 announced its entry in the SSD contro..

JFFS2 overview & JFFS3 Requirements Abstract JFFS2, the Journalling Flash File System version 2, is widely used in the embedded systems world. It was designed for relatively small flash chips and has serious problems when it is used on large flash devices. Unfortunately, these scalability problems are deep inside the design of the file system, and cannot be solved without full redesign. This document describes JFFS3 – a new flash .. NAND Flash (NAND vs. NOR) NAND FLASH NAND vs. NOR Beside the different silicon cell design, the most important difference between NAND and NOR Flash is the bus interface. NOR Flash is connected to a address / data bus direct like other memory devices as SRAM etc. NAND Flash uses a multiplexed I/O Interface with some additional control pins. NAND flash is a sequential access device appropriate for mass storage application.. 이전 1 다음
