请问各位朋友一个小问题，K64中Flash Memory Module (FTFE)和Flash Memory Controller (FMC)有什么区别？是不是两个模块都可以读写Flash和Ram中的数据。

楼主你好。
FMC的说明：
The Flash Memory Controller (FMC) is a memory acceleration unit that provides:
• an interface between the device and the dual-bank nonvolatile memory. Bank 0
consists of program flash memory, and bank 1 consists of FlexNVM.
• buffers that can accelerate flash memory and FlexNVM data transfers.
FTFE的说明：
The FTFE module includes the following accessible memory regions:
• Program flash memory for vector space and code store
• For FlexNVM devices: FlexNVM for data store and additional code store
• For FlexNVM devices: FlexRAM for high-endurance data store or traditional RAM
• For program flash only devices: Programming acceleration RAM to speed flash
programming

通常的flash ，FlexNVM的操作是通过FTFE实现的。

FMC是控制器，是执行机构，没Flash，只有一堆寄存器（顺带有点cache），FTFE是真正的Flash存储阵列
