Abstract
A data-processing device is provided. The data-processing device includes: a flash memory, a computation unit, and a flash-memory controller. The flash-memory controller is electrically connected to the computation unit, and configured to control access to the flash memory. The flash-memory controller allocates a first execute-only memory (XOM) setting and a second XOM setting in a first memory bank and a second memory bank of the flash memory, respectively. The flash-memory controller allocates one or more XOM spaces in the flash memory according to the first XOM setting or the second XOM setting.
