spi nand flash

SPI NAND Flash是一种使用SPI串行接口的NAND Flash芯片。与传统的NAND Flash相比，SPI NAND Flash具有更小的封装尺寸和更低的成本。SPI NAND Flash的操作以块为基本单位，每个块通常为8KB，并且每个块又分为多个页，每页大小一般为512字节。与Nor Flash相比，SPI NAND Flash在硬件上更容易兼容不同容量的芯片，并且占用更小的PCB板位置。但是，要修改SPI NAND Flash芯片中的一个字节，需要重写整个数据块，读写操作都是按照扇区进行的。因此，SPI NAND Flash在一些特定的应用场景下具有一定的优势。\[1\]\[2\]\[3\]
