Execute-only memory (XOM) allows only instruction fetches. Read and write accesses are not allowed.
Execute-only memory allows you to protect your intellectual property by preventing executable code being read by users. For example, you can place firmware in execute-only memory and load user code and drivers separately. Placing the firmware in execute-only memory prevents users from trivially reading the code.
