asked on 

what is SD card, eMMC, NAND interface?

How do I communicate (interact) with:

1) microSD card
2) eMMC
3) NAND Flash
4) Most flash memory units

I know we can interact with a microSD card through SDIO or SPI (not recommended).

Depends..., on laptops mostly there is a USB involved.  and a USB -> MMC or SD controller.
Raspberry Pi uses GPIO. for uSD.

I want to communicate using a SOC or MCU chip.
Also, I don't want to use a USB bridge (i.e. USB to eMMC bridge). I want to directly connect to my flash memory (NAND Flash, eMMC, etc.)
