Must have been hiding under a rock, but just discovered this eMMC stuff.
If I have it right, it's similar to SPI mode uSD, but with 8-bit bus and high speed.
Maybe I ignored it before due to BGA and lots of balls.
But, when I see it now, only a few of the balls are actually used.
All in all, not much different from HyperFlash.
But, memory size is much bigger with eMMC.
So, why use HyperFlash?
Maybe writing is faster? Just lower cost and size?
