Abstract: A dynamic random access memory (DRAM) device is provided. The DRAM device includes a circuit substrate, a light emitting element, a first light-permeable thermal dissipation element, and a first light blocking element. At least one DRAM chip is disposed on the circuit substrate. The light emitting element is disposed on the circuit substrate and coupled to the circuit substrate. The first light-permeable thermal dissipation element is disposed on the circuit substrate. The first light blocking element is disposed between the first light-permeable thermal dissipation element and the circuit substrate, and the first light blocking element is disposed on the first light-permeable thermal dissipation element.

Abstract: This application provides an electronic device, including: a processor, configured to select one of an absolute coordinate mode and a relative coordinate mode according to a switching instruction. When the processor uses the absolute coordinate mode, absolute coordinate information received by the processor is run in the absolute coordinate mode; and when the processor uses the relative coordinate mode, the absolute coordinate information received by the processor is converted into relative coordinate information and is run in the relative coordinate mode. Therefore, this application performs adaptive conversion between the absolute coordinate mode and the relative coordinate mode, to provide users with more flexible operations.
