Flash Translation Layer - FTL for NAND

FTL: Flash Translation Layer source code product for NAND flash chips.

Flash Translation Layer Overview

Flash 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 160 million flash based devices (TransFlash Cards, SD cards, CF Cards, USB flash drives, 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.
