NOR Flash for a FPGA configuration

Hey, I have a NOR flash in order to configure my FPGA (cyclone V in this case). I have read the principle of a NOR flash operation and I have two questions: 1) What exactly happens in the erase o...

Hi,


In erase operation, NOR Flash will become 0xffffffff, it will become 0x00000000 if it is NAND flash.


NOR flash cell in its default state is logically equivalent to a binary "1" value, because current will flow through the channel under application of an appropriate voltage to the control gate, so that the bitline voltage is pulled down
