Since you hinted at having tested the chip yourselves awhile back, I'm wondering how specifically it effects the speed? My theory was it had to do with the number of bits grayscale being used. Is this accurate, or is there something else going on?
Many thanks,

PS It's good to know that the EZ reader is fairly resistant. I've been a little skittish to buy a new reader since the screen on my Sony reader broke (I still may ultimately wait for the plastic screens though). |
Dear Dylan:
I have NOT specifically tested the Epson controller but know well how it works. My company also manufactures Flash Memory Cards which also work with NAND Flash and a controller. Single Level Cell is far faster than Multi Level Cell NAND. Unfortunately, two years ago, all of the NAND manufacturers went to Multi Level Cell 90%. That means the cost of SLC went sky high.
What the Epson Controller does is have an interface that will allow info to be pulled from both levels at once (think of a Multi Level Nand as a two-story house). It means instead of running up and down stairs to find your socks, umbrella, and running shoes... you and your mate split up and hunt both floors simutaneously.
As all those bytes of ebook are stored in the NAND Flash, the search takes much shorter time.
Does that help?
