John: Actually, as I said, I'm not an expert. And I would appreciate any information you could give me to help me understand the category.

Fair enough. I hope you excuse the unkind language, but your post provoked me: I'm surprised AMD is still strictly NOR. Could be the reason they did not honor the AMD contract. Maybe a design win by a competitor with NAND? Another excuse for Alcatel, AMD just didn't keep up with the technology?

As for an explanation of NAND vs NOR, combjelly has _just_ posted a good pointer:

Message 15616078

Are you saying that NOR and NAND cannot be designed into the same applications?

see combjelly's post.

Are you saying that NOR is always a more elegant solution than NAND?

"elegant" is a loaded word if I ever heard one ;). NAND has the ability to offer higher densities and lower costs per bit. In some situations, that's "elegant". In other situations, you really need to low latency, high number of read/write cycles.

Are you saying that the density capability of NOR is higher than NAND?

No, see above.

Are you saying that NOR flash is the future, rather than NAND?

Well... NOR generally has better operational characteristics than NAND, but its more expensive. Both would seem to have a place, but they are not generally interchangeable.

What exactly are you saying?

AMD is, without doubt, the premier supplier of NOR flash. And to suggest, as I definitely feel your post does, that AMD "just didn't keep up with technology" is... well... ludicrous. Take a peek at the awards AMD's memory group has won just last year:

Cisco President's Customer Satisfaction Award
2000 Samsung Best Supplier Award
QS-9000 Certification
Nortel Supplier of theYear
Cisco Systems Supplier of the Year 1999 (awarded in 2000)

(http://www.amd.com/products/nvd/awards/awards.html)

If you need low voltage, a large number of read/write cycles, low latency etc., you go with AMD flash. It isn't the cheapest on the market, but it is the best.

I know nothing about flash but I have this comment on your questions:
Anything is possible; if you have no limits on how much money/power/effort you are going to put into making it. Which suggests that the broad and contextless questions you are asking are just inflammatory and serve no purpose of getting information as you claim to seek.

John, converting from NOR to NAND can probably be done with the addition of SRAM or FIFO buffers and an FPGA to control the interface, depending on the application.
