  • Storage Solutions for Embedded Applications
    White Paper Storage Solutions Brian Skerry Sr. Software Architect Intel Corporation for Embedded Applications December 2008 1 321054 Storage Solutions for Embedded Applications Executive Summary Any embedded system needs reliable access to storage. This may be provided by a hard disk drive or access to a remote storage device. Alternatively there are many flash solutions available on the market today. When considering flash, there are a number of important criteria to consider with capacity, cost, and reliability being foremost. This paper considers hardware, software, and other considerations in choosing a storage solution. Wear leveling is an important factor affecting the expected lifetime of any flash solution, and it can be implemented in a number of ways. Depending on the choices made, software changes may be necessary. Solid state drives offer the most straight forward replacement option for Hard disk drives, but may not be cost-effective for some applications. The Intel® X-25M Mainstream SATA Solid State Drive is one solution suitable for a high performance environment. For smaller storage requirements, CompactFlash* and USB flash are very attractive. Downward pressure continues to be applied to flash solutions, and there are a number of new technologies on the horizon. As a result of reading this paper, the reader will be able to take into consideration all the relevant factors in choosing a storage solution for an embedded system. Intel® architecture can benefit the embedded system designer as they can be assured of widespread

These highly‐integrated silicon devices address the inherent endurance, reliability, and data retention issues associated with NAND flash memory, making it possible to build SSDs that deliver unprecedented performance over the life of the drive with orders‐of‐magnitude higher reliability than enterprise‐class HDDs (Hard Disk Drives). The SandForce patent‐pending DuraClass™ technology promises to accelerate mass‐market SSD adoption. Leading OEMs are expected to release both SLC (single level cell) and MLC (multi‐level cell) flash‐based SSDs using SandForce single‐chip SSD Processors later this year. IDC expects worldwide shipments of SSD's in the Enterprise and PC markets will exceed 40 million units in 2012, representing a CAGR of 171% from 2007‐20121. “The SF‐1000 SSD Processor Family promises to address key NAND flash issues allowing MLC flash technologies to be reliably used in broad based, mission critical storage environments,” said Mike Desens, Vice President for System Design, IBM.

  • Wear Leveling Architecture and Read Disturbance Technology for Solid-State Drives
    An InnoDisk White Paper August 2012 Wear Leveling Architecture And Read Disturbance Technology For Solid-State Drives Prolonging SSD Lifespan And preventing Read Disturbance InnoDisk’s Wear Leveling Architecture and Read Disturbance Technology 0 Revision History Date Version Information 2012.07.09 1.0 First Release Introduction This white paper presents InnoDisk’s wear leveling process for prolonging the lifespan of a solid-state drive (SSD) and preventing read disturbance. Conventional file systems like FAT, UFS, HFS, ext 2 and NTFS were originally designed for magnetic strips and as such rewrite data repeatedly to the same area. However, SSDs can be put through a limited number of erase cycles before becoming unreliable. This is usually around 3,000/100,000(MLC/SLC) cycles. Wear leveling works around these limitations by spreading erasures and re-writes across multiple blocks in an SSD. In this way, no single block is subjected to constant read/writes. How InnoDisk’s Wear Leveling architecture and technology prolongs SSD lifespan and prevents read disturbance InnoDisk uses a combination of two types of wear leveling – dynamic and static wear leveling – to distribute write cycling across an SSD. Both types of wear leveling use a map to link Logical Block Address (LBAs) from the OS to the physical Flash memory. Static wear leveling, however, differs in that static blocks that do not change are periodically moved so that low usage cells are able to be used by other data. System Buffer Blocks and Dynamic Wear Leveling Because Flash blocks can’t be overwritten, some spare blocks need to be reserved for temporary data buffering.

  • A High-Performance Wear- Leveling Algorithm for Flash Memory System
    LETTER IEICE Electronics Express, Vol.9, No.24, 1874-1880 A high-performance wear- leveling algorithm for flash memory system Ching-Che Chung1a), Duo Sheng2, and Ning-Mi Hsueh1 1 Department of Computer Science & Information Engineering, National Chung- Cheng University, 168 University Road, Min-Hsiung, Chia-Yi 621, Taiwan 2 Department of Electrical Engineering, Fu Jen Catholic University, 510 Chung-Cheng Rd. Hsin-Chung, Taipei 24205, Taiwan a) [email protected] Abstract: In this paper, a low-complexity high-performance wear- leveling algorithm which named sequential garbage collection (SGC) for flash memory system design is presented. The proposed SGC outperforms existing designs in terms of wear evenness and low design complexity. The lifetime of the flash memory can be greatly lengthened by the proposed SGC. The proposed SGC doesn’t require any tuning threshold parameter, and thus it can be applied to various systems without prior knowledge of the system environment for threshold tuning. Simulation results show that the maximum block erase count and standard deviation of the block erase count compared to the greedy algorithm are decreased by up to 75% and 94%, respectively.

  • Wear Leveling in Micron® NAND Flash Memory
    TN-29-61: Wear Leveling in NAND Flash Memory Introduction Technical Note Wear Leveling in Micron® NAND Flash Memory Introduction This document describes the recommended wear leveling algorithm to be implemented in the flash translation layer (FTL) software for Micron® NAND Flash memory. Wear Leveling and the Flash Translation Layer In Micron single-level cell (SLC) and multilevel cell (MLC)NAND Flash memory, each physical block can be programmed and erased reliably up to 100,000 and 10,000 times, respectively. For write-intensive applications, it is recommended to implement a wear leveling algorithm to monitor and spread the number of write cycles per block. In memory devices that do not use a wear leveling algorithm not all blocks get used at the same rate. The wear leveling algorithm ensures that equal use is made of all the available write cycles for each block. Wear leveling is implemented in the flash translation layer (FTL), which is the additional software layer between the file system and the NAND Flash memory. The FTL allows operating systems to read and write to NAND Flash memory devices in the same way as disk drives and provides the translation from virtual to physical addresses. Wear leveling can also be implemented by the file system directly on the NAND Flash (see Figure 1). Refer to the data sheets for the full list of root part numbers and for further information on the devices (see “References” on page 5).
