Abstract
A semiconductor device includes a first processing unit configured to perform a calculation by using data stored in a memory; and a memory path controller configured to communicate with the first processing unit and control the memory for the first processing unit to perform the calculation, wherein the memory path controller includes an address region control unit configured to divide an address space of the memory to include a secure address and a non-secure address and permit the first processing unit to access the secure address or the non-secure address, and a first content firewall unit connected with the address region control unit and configured to prevent the first processing unit from writing secure contents in the non-secure address.
