In an embodiment, a system comprises: a first bus; a second bus; a first peripheral coupled to the first bus and the second bus, the first peripheral configured to receive a command from the first bus and to generate data in response to the first command; and a second peripheral coupled to the first bus and the second bus, the second peripheral configured to initiate transfer of the generated data from the first peripheral to the second peripheral over the second bus such that access to the generated data through the first bus is prevented.

System architecture with secure data exchange

A memory controller includes a generator circuit configured to generate a predetermined pattern of data, an address input, and a memory interface circuit. The memory interface circuit is configured to write the predetermined pattern of data to a memory at an address identified in the address input. The memory interface circuit is further configured to read a stored pattern of data from the memory at the address. The memory controller further includes an integrity checker circuit configured to compare the predetermined pattern of data and the stored pattern of data and identify an error of the memory based upon the comparison.

Safety enhancement for memory controllers

An apparatus includes an interface for dynamic random access memory (DRAM); and an integrated circuit. The integrated circuit includes a memory pinout configured to connect to the memory and control logic. The control logic is configured multiplex address information, command information, and data to be written to or read from the DRAM memory on a subset of pins of the memory pinout to the DRAM memory. The control logic is further configured to route other signals on other pins of the memory pinout to the DRAM in parallel with the multiplexed address information, command information, and data information.

Access to DRAM through a reuse of pins
