SPI Flash （即SPI Nor Flash）是Nor Flash的一種，NOR Flash根據(jù)數(shù)據(jù)傳輸?shù)奈粩?shù)可以分為并行（Parallel）NOR Flash和串行（SPI）NOR Flash，SPI Nor Flash每次傳輸一個(gè)bit位的數(shù)據(jù)，parallel Nor Flash每次傳輸多個(gè)bit位的數(shù)據(jù)，SPI Nor Flash比parallel便宜，接口簡單點(diǎn)，但速度慢。NOR Flash是一種非易失性的存儲(chǔ)器，具有存儲(chǔ)容量大，數(shù)據(jù)保存時(shí)間長的特點(diǎn)，其擦寫次數(shù)多達(dá)10萬次，數(shù)據(jù)更新速度比EEPROM要快很多，在斷電的情況下也能保存數(shù)據(jù)，常用來保存一些重要的配置信息。
