摘要： A system on chip (SoC) including a memory management unit (MMU) and a memory address translation method thereof are provided. The SoC includes a master intellectual property (IP) configured to output a request corresponding to each of a plurality of working sets; an MMU module comprising a plurality of MMUs, each of which is allocated for one of the working sets and translates virtual addresses corresponding to the request into physical addresses; a first bus interconnect configured to connect the MMU module with a memory device and to transmit the request, on which address translation has been performed in at least one of the MMUs, to the memory device; and a second bus interconnect configured to connect the master IP with the MMU module and to allocate one of the MMUs for each of the working sets.

摘要： A method for detecting a storage voltage, a display apparatus using the storage voltage and a method for driving the display apparatus. The method for detecting the storage voltage includes applying a test voltage to a storage line in a display panel having an active layer disposed between the storage line and a data line while varying the test voltage, the active layer being in an active state or an inactive state according to the test voltage, and detecting the storage voltage corresponding to the test voltage in an inactive state of the active layer. Thus, the display panel is driven by using the detected storage voltage, so that an aperture ratio may be increased and current consumption may be decreased.
