S 29394 is an eeprom produced by Seiko.
I have a GQ4x which does not support this chip.
Is there any way to use my programmer to read it and write it
Any advice

Thanks a lot. I'll try it soon.
But this seems to be very simple.
Did you take in consideration the different : pins arrangement;frequency and read/write volt.
