Wily,

AMD is boasting 64 Mbit multicell flash by early 2002.

WHOOPEEEEEE!

The press release suggests that the Mirror Bit flash is a monumental breakthrough
and underscores reliability issues with current generation MLC products.

My interpretation is that their timeline significantly lags the industry leaders,
although AMD may benefit handsomely from the effective doubling of capacity
afforded by their multicell breakthrough. This benefit may be at the expense of
competitors in the moderately high density flash market. Right now SNDK does
not serve this particular segment of the flash market.

Mirror Bit ain't MLC

I don't see how this innovation relates to MLC. The concept is quite
different. Perhaps MLC is just mentioned to contrast the attributes of
new AMD product and to highlight the inherent difficulties with MLC technology.
The fact of the matter is that Eli has outlined 3 or more bits per cell in
his technology roadmap with technology already available that can decipher
more than 100 unique voltages per cell. I am not sure how Mirror Bit will
be able to keep up with MLC unless it is based on performance rather
than bit density.

"The Mirror Bit architecture's ability to store two bits of data in one cell, without compromising data integrity, is achieved by dividing each standard cell into two discrete and independent units where the data is stored in physically distinct locations."
