An electronic apparatus has a stand-by mode. The electronic apparatus includes a first circuit, a second circuit and a third circuit. The first circuit has an interface and transfers data to an external device. The second circuit has a processor and sets a first power supplying mode of the first circuit. The third circuit sets a second circuit power supplying mode of the second circuit and sets a second power supply mode of the first circuit when the second circuit is disabled. The processor selects a first circuit power supplying mode from power supplying modes of the first circuit as the second power supplying mode before the second circuit is disabled.

A bus integrating system is applied to a data processing system. A bus controlling module is coupled to at least one peripheral device for enabling a corresponding device to access data according to a data access request signal sent from the peripheral device. A bus integrating processor includes at least one first bus data access signal pin and at least one second bus data access signal pin, so as to allow the bus controlling module to control peripheral devices connected to buses of a first data transmission standard and a second data transmission standard to perform data access with another peripheral device of the same and different data transmission standard via the single bus integrating processor. Thereby, the bus integrating system allows buses with different data transmission standards to transmit data via a single bus and the integrating bus controlling module.

A conversion interface of memory device is provided for converting a current operating command of a user's software program to an operating command capable of being executed by the memory device. The conversion interface includes a command decoding module and a command generating module. The command decoding module receives the operating command of the user's software program and decodes the operating command to a decoding command, such that the command generating module generates the operating command capable of being executed by the memory device according to the decoding command. This can realize compatibility between a current software program and a new type of memory device, thereby effectively reducing the design costs and product development cycle and providing great flexibility in design.
