Abstract
The invention includes a system and method of modifying a setting of a NAND flash memory device using serial peripheral interface (SPI) communication from a master to the NAND flash memory device. One embodiment generally includes sending an enable signal to a first memory circuit input, sending a clock signal to a second memory circuit input, sending a command signal synchronized to the clock signal to a third memory circuit input, sending a memory register address signal synchronized to the clock signal to the third memory circuit input, and sending a setting signal synchronized to the clock signal to the third memory circuit input.
