You can get all the articles/source from 1988 up to now on the Dr. Dobb's CD/Release 9: http://www.ddj.com/cdrom/ It's $100US though. Here's a list of the FLASH articles that I found on my Release 8 CD: May 93 FLASH FILE SYSTEMS by Drew Gislason Flash memory packaged in solid-state, credit card-size PCMCIA cards is starting to change the face of embedded and portable systems. Drew examines Flash file systems and presents one that's FAT-like. Feb 95 THE MICROSOFT FLASH FILE SYSTEM by Peter Torelli Peter examines flash file systems for DOS, focusing on the mechanics behind a flash file system based on the Microsoft data structures. Oct 95 INSIDE FLASH MEMORY by Brian L. Dipert Direct-execute flash memory systems don't require the gigabyte hard disks and 64-Mbit DRAM arrays common in desktop systems. The May 93 article has source that simply allocates a FLASH sector for every sector of a FAT file system. It doesn't do erases. He discusses that there is a better way, which he called "Byte-oriented Flash File System", but there isn't much detail there. What he does say is that at Datalight (his employer) they use a linked list of records with each header containing "approximately 12 bytes (describing the data's owner) and a variable-length data field". I do not see any mention of an FTL. This last point interested me because the article is from May 93 and the imfamous M-systems patent was filed Mar 93.
