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