The resistive random access memory controller (RRAMC) is used for writing the internal RRAM memory, , and the user information configuration registers (UICR).
The main features of RRAMC are:
- Write and overwrite without erasing
- 64-bit word line with built in error correction code (ECC), detecting and correcting up to two bit errors per line
- Automatic standby or power-down modes
- One-time programmable (OTP) protection for user information configuration registers (UICR)
- Optional immutable boot region protection
