Abstract

In an embodiment, a system employs encryption on memory addresses generated by a source circuit that generates memory transactions (e.g., a processor such as a central processing unit (CPU), a graphics processing unit (GPU), various embedded processors or microcontrollers; or a peripheral device. The encrypted memory address corresponds to the row that is activated for the memory transaction, instead of the memory address generated by the source circuit.
