GENERAL DESCRIPTION
Serial peripheral interface (SPI) NAND is an SLC NAND Flash memory device that provides a cost-effective nonvolatile memory storage solution where pin count must be kept to a minimum. It is also an alternative solution to SPI NOR, offering superior write performance and cost per bit over SPI NOR. The hardware interface creates a low pincount device with a standard pinout that remains the same from one density to another and supports future upgrades to higher densities without board redesign.
