Flash Translation Layer - FTL for NANDFlash Translation Layer OverviewFlash Translation Layer (FTL) from Zeeis is the small footprint, high performance NAND flash data manager to support sector-based file systems (FAT, NTFS, etc.) to operate Single Level Cell (SLC) and Multi Level Cell (MLC) NAND flash chips like any other block storage device. It makes NAND flash memory device appear to the system like a disk drive.Zeeis Flash Translation Layer have integrated in over 16 million flash based devices - TransFlash Cards, SD cards, CF Cards, USB flash drives, solid-state drives (SSD), MP3 players and mobile phones.FTL is a translation layer between the sector-based file system and NAND flash chips. It enables the operating system and file system access NAND flash memory devices as access disk drives. Wear leveling algorithms are implemented for prolong the NAND flash chips lifetime, that monitors and spreads the number of Page Program(Write) and Block Erase cycles across the entire NAND flash chip.FTL has been fully tested for use with a wide range of NAND flash chips and it supports NAND flash chip arrays to increase capacity and performance.Flash Translation Layer FeaturesHigh performance and reliable NAND FTLSupports all SLC and MLC NAND flash chipsSupports small page and large page (528, 2112 and 4224 bytes page size)Bad Block Management HandlerECC module includedFast Garbage CollectionPower-fail recoveryWear leveling100% ANSI C source code for guaranteed portabilitySimple API offers a very easy way to build flash-based storage device.Optimized performance and reliability for limited resources MCUs/DSPsRAM and ROM resources usage highly scalable by configurable featuresProcessor and RTOS independent1 year free technical support for unlimited number of support cases3 year free upgradesRoyalty-free & Business-friendly License Flash Translation Layer API SummaryFTL_mountMount the drive and create the cache buffer for FTL.FTL_unmountFree all resources of the FTL.FTL_formatFormat the drive.FTL_sectorsGet maximum usable sectors number of this FTL drive.FTL_readRead sectors from FTL drive.FTL_writeWrite data to sectors of FTL drive.Flash Translation Layer Application Programming InterfaceFTL_mountFTL_STATUS FTL_mount(void)Mount the drive and create the cache buffer for FTL.ReturnsFTL_SUCCESS for success, else an error code is returned.FTL_unmountFTL_STATUS FTL_unmount(void)Free all resources of the FTL.ReturnsFTL_SUCCESS for success, else an error code is returned.FTL_formatFTL_STATUS FTL_format(void)Format the drive.ReturnsFTL_SUCCESS for success, else an error code is returned.FTL_sectorst_sec long FTL_sectorsGet maximum usable sectors number of this FTL drive.ReturnsThe number of total sectors.FTL_readt_sec FTL_read(void *buffer,t_sec sector,t_sec count)Read sectors from FTL drive.ParametersbufferStorage location for data.sectorThe logical sector numbercountMaximum number of sectors to be read.ReturnsThe number of full sectors actually read, which may be less than count if an error occurs.FTL_writet_sec FTL_write(void *buffer,t_sec sector,t_sec count)Write data to sectors of FTL drive.ParametersbufferPointer to data to be written.sectorThe logical sector numbercountMaximum number of sectors to be write.ReturnsThe number of full sectors actually written, which may be less than count if an error occurs.Licensing and PricingZeeis Flash Translation Layer is a low-cost and royalty-free software IP designed to enable developers design their own final products quickly and easily, so there are no restrictions or limitations on the use or modification for your products.Please contact us or send email to sales@zeeis.com for further information.5010150-33083500Flash Translation Layer - NAND FTLFor technical questions about Zeeis products and services, please contact our support team: support@zeeis.comFor help purchasing from Zeeis, please contact our global sales team: sales@zeeis.comFor more information please visit Zeeis FTL website: http://www.zeeis.com/flash-translation-layer/Copyright © 2007, 2008, 2009, 2010, 2011 Zeeis.
