Psoc is uses flash to store code and system configuration. Using fram instead of flash could enable:
1. lower power
2. instead of optimizing memory size for 2 both ram and flash size,use one memory and let designer use it as it will. this will enable smaller size, less need for psoc variations and easier and more varied use.
3. write speed is much faster for fram, which enables faster reconfiguration. might enable better ways to design stuff.
4. higher fram endurace.
