Good picture 
Seems to be the right chips, a 32 MBit and a 64 MBit 3V spi. You need a CH341 programmer and a SOIC8 clip to read them. There’s a lot written how to do that in the forum- for example:
Placing the clip is a pain in the beginning. You need two 100% identical reads of every chip to be sure that your dumps are valid. Compare with HxD or if you prefer to work with checksums: Check in addition the structure with UEFIToolNE (Files with all ‘FF’ do have e nice looking checksum, too)
If you can’t read you possibly can’t write- so it’s useful to read first to be sure that the handling of clip and program is OK (even if you’re sure you have already a valid backup and are sure that the chip content isn’t useful any longer).
