Nand flash layout and Eeprom issue

 Hi!  I have a couple of questions about the CY7C68023 nand flash controller.

1. Can I connect a 2Gbytes Dual-Die Nand Flash? Datasheet says that it only supports 1Gbyte max. size ones... I think It refers to 1Gbytes max per Chip Enable, so if I connect a 2Gbytes dual-die one (it needs 2 CE lines) it should work correctly... am I wrong?

2. Is the spi eeprom really needed? I'd like to design a very simple USB 2.0 mass storage device (2Gbytes size) and I think I could use the default rom values... 

Kind regards.

1. Yep. Your understanding is right.

2. The part you're referring to is NX2LP and it does not support EEPROM at all. I'm confused as to which document you're referring.

Regards,

Anand
