# 1.18 MCRAMC ECC with Fault Injection and MBIST Testing

This example application demonstrates how to test the SRAM using MBIST and the MCRAMC ECC feature on internal SRAM memory.

## Description

This example uses the SMBIST peripheral library to test the SRAM at boot time and the MCRAMC to test its ECC with Fault Injection feature. This application writes a 32-bit data in SRAM for single and double error injection to highlight SEC and DED process.
