Nor flash structure
Web2.2 Configuring FlexSPI NOR FLASH. The structure of FLEXSPI NOR FLASH configuration parameters is complex but there is a simple way to use it. To encode FCB, NXP defines two . uint32_t. variables, option0. and . option1. In most cases, configure only . option0. and leave . option1 . as . 0x0000_0000. Web但是NOR Flash也有一些缺点,比如它的单元尺寸较大,导致每比特单位成本高于其他 Flash,同时它的写入和擦除速度也稍慢。 综上所述,NOR Flash是对容量需求不高但需要快速随机读取访问和更高数据可靠性的应用的理想选择,例如代码执行及关键数据的存储。
