An electronic circuit comprising an SRAM memory, a control unit, an error detection and correction module and a scrubbing module. The electronic circuit further comprises an integrated SEU monitor of the SRAM memory. The SEU monitor does not use standalone or specialized SRAM memories or particle detectors. Rather, the same SRAM memory that is used for the main operation as a storage element of the electronic circuit serves simultaneously as detector for the SEU monitor. The proposed SEU monitor enables real-time monitoring of the SEU rate in order to detect early the high radiation levels and apply appropriate hardening measures. Furthermore, a method for monitoring an SEU rate and determining permanent faults in an electronic circuit is suggested.
