What are the structural differences between Serial NOR Flash and Parallel NOR Flash? If there is a structural difference , then What are the differences between Serial NOR Flash and Serial NAND Flash? I can't seem to get the resource for this particular question from Googling
Answer
Serial flash uses serial bus to write and read the data from the device. Popular serial buses include I2C and SPI. Serial signaling involves address, data and control signals on 2-3 wires.
Parallel flash uses parallel 8 Bit I/O or Bus to write and read the data from the device. Parallel signals needed are Data bus (usually 8 bit), address bus (depends on device density) and control bus (en, oe).
I could have added more details but the question is too generic, hence generic answer.
