Abstract
A system and method of utilizing ECC memory to detect software errors and malicious activities is disclosed. In one embodiment, after a pool of memory is freed, every data word in that pool is modified to ensure that an ECC error will occur if any data word in that pool is read again. In another embodiment, the ECC memory controller is used to detect and prevent non-secure applications from accessing secure portions of memory.
