Does that include the memory controller for it, and all the other external circuit?
Remove the discrete NAND, and put an eMMC, and like I said, it's about 3 bucks, perhaps less... as eMMC is on the right side of the pricing/supply curve, and the old school NAND is on the downside, esp as FAB's are moving in that direction... moving from SLC NAND to MLC/TLC and 3D-VNAND technology - at some point, producing old-school NAND will not be profitable...
It's not that much of a cost adder, as MMC is similar to SDIO - the eMMC is self-hosting with it's own controller, so it's a matter of running the lines out to the single eMMC chip, and enabling the driver in the OS...
In any event, discrete NAND chips, both for expansion via JFFS, and real-time (where that address block must be mirrored into RAM) is 2005 technology in applications built around the Broadcom SDK, which I'm reasonably certain that we can both agree is getting long in tooth - being based largely on the Linksys WRT54G GPL drops from even before (and OPKG being based on Unslung which goes back to... NSLU2...)
Think about the advantages of eMMS and a real file system - one can do OverlayFS (or AUFS if one wants to be really bold) - this offers the opportunity to do targeted fixes without having to rebuild the entire flash image - and this is huge considering the security risks that we're facing these days - just fix the lib or application in place... Entware/Optware is kinda there already, but this is an add-on, can you imagine the benefits here for both off-the-shelf and carrier provided equipment?
I can...
