Does SDFat support SPI flash chips instead of SD Cards?

I'm trying to replace SD card for an SPI flash chip.
Can I use the SDFat to directly access and use SPI flash chips instead of SD cards?

As far as I know the SD library has specifically been written to communicate with an SD card controller on the SD card and NOT to communicate with any first that comes along chip on the SPI bus, so IMO I'm fairly sure that the answer to your question is NO.
