Embedded memory are important components in system-on-chip, which may be crippled by aging and wear faults or Hardware Trojan attacks to compromise run-time security. The current built-in self-test and pre-silicon verification lack efficiency and flexibility to solve this problem. To this end, we address such vulnerabilities by proposing a run-time memory security detecting framework in this paper. The solution builds mainly upon a centralized security detection controller for partially reconfigurable inspection content, and a static memory wrapper to handle access conflicts and buffering testing cells. We show that a field programmable gate array prototype of the proposed framework can pursue 16 memory faults and 3 types Hardware Trojans detection with one reconfigurable partition, whereas saves 12.7% area and 2.9% power overhead compared to a static implementation. This architecture has more scalable capability with little impact on the memory accessing throughput of the original chip system in run-time detection.
