Testing read-only memory using memory built-in self-test controller

A non-transitory storage device storing instructions, which when executed by a central processing unit (CPU), causes the CPU to:

• copy a plurality of instructions from a range of addresses within the non-transitory storage device to a volatile storage device;
• alter a program counter to correspond to an address in the volatile storage device;
• and
• determine whether the non-transitory storage device has passed a test performed by a second device.

A method, comprising:

• copying a plurality of instructions from a range of addresses within a read-only memory (ROM) to a volatile storage device;
• changing a value of a program counter to correspond to an address within the volatile storage device at the beginning of the plurality of instructions;
• alter the value of the program counter to correspond to an address within the ROM;
• and
• determining whether the ROM passed a test.
