Abstract: A display device according to an embodiment includes a display, a first power module that outputs a first power, and a second power module that outputs a second power. The first power and the second power are supplied to the display. The first power module is configured to cut off the first power when an amount of input current exceeds an overload criterion, to identify whether the second power module is abnormal based on the second power, and to change the overload criterion from a first threshold current amount to a second threshold current amount that exceeds the first threshold current amount, in an abnormal state of the second power module.

Abstract: A controller is provided. The controller creates a page table including page table entries including mapping information for translating a virtual address to a physical address. Each of the page table entries includes: a virtual page number, a physical frame number, valid information, and size information. The virtual page number is included in a virtual address, the physical frame number is included in a physical address, the valid information includes a first predetermined number of bits, and the size information includes a second predetermined number of bits. The first predetermined number of bits represents an address translation range in a page table entry or a number of page table entries to be grouped, and the size information represents a size indicated by each bit of the first predetermined number of bits.
