Difference between SPI FLASH and NOR FLASH

1, SPI Flash (i.e. SPI Nor Flash) is a kind of Nor Flash;

2, NOR Flash can be divided into parallel (Parallel) NOR Flash and serial (SPI) NOR Flash according to the number of bits of data transmission;

3, SPI Nor Flash transmits one bit of data at a time, and parallel Nor Flash transmits more than one bit of data at a time (there are two kinds of x8 and x16bit);

4, SPI Nor Flash is cheaper than parallel, the interface is simpler, but slower.

SPI FLASH is the external interface in line with the SPI protocol, which is the serial port.

NOR FLASH and NAND is relative, referring to the serial and parallel within the chip.

SPI FLASH is a kind of NOR FLASH.
