Abstract
A secure memory interface includes a reader block, a writer block, and a mode selector for detecting fault injection into a memory device when a secure mode is activated. The mode selector activates or deactivates the secure mode using memory access information from a data processing unit. Thus, the data processing unit flexibly specifies the amount and location of the secure data stored into the memory device.
Claims20
A secure memory interface comprising:
- a writer block that generates a final write data to be written to a memory device from initial write data and error detection code when a secure mode is activated;
- and
- a mode selector for activating or deactivating the secure mode using memory access information from a data processing unit.
A method of securely accessing a memory device, the method comprising:
- generating a final write data to be written to the memory device from initial write data and error detection code when a secure mode is activated;
- and
- activating or deactivating the secure mode using memory access information from a data processing unit.
