Hi thats my first post here!, and im happy to be here :). im a beginner please be patient with me.

let me explain my question,
I have seen that we can use ยต-controllers and arduino to read/write data using SPI with SD-CARDs.
So,would it be possible to read a SPI flash memory (like Winbond) using a conventional USB SD card reader?

Please, if it's possible tell me how(that would be fun), and if it isn't tell me why
thanks for your attention.

It is impossible, because SPI is just a fallback mode for SD card, and it uses protocol different from typical SPI flash ICs.

SD Card readers use SD mode, not SPI.

You could, however, make an SD card controller and connect it to an SPI flash to effectively use it as an SD card...
