A bus interface device for requesting and receiving data from a memory controller connected to a bus includes a request buffer and a request merger. The request buffer is configured to store a first data request signal for requesting first data and a second data request signal for requesting second data. The request merger is configured to determine whether to merge the first and second data request signals, and transmit a merged request signal for requesting the first data and the second data from the memory controller to the bus upon determining that the first and second data request signals are to be merged.

A method of operating a semiconductor memory device includes receiving a timeout index signal corresponding to a master of the first master group based on a residual capacity of a data buffer of the first master, setting a first timeout value in response to the timeout index signal, and changing an execution order of commands stored in a queue of the semiconductor memory device based on a result of counting the first timeout value and counting a second timeout value corresponding to a master of the second master group.

A mobile System on Chip (SoC) including a central processing unit (CPU) and an audio out module that includes a buffer and an audio interface. A power mode of the audio out module is controlled separately from a power mode of the mobile SoC so that the audio out module operates when the mobile SoC is in a power down mode.

A buffer memory for rotating an image. The buffer memory is address-mapped in three dimensions including a first axis, a second axis, and a third axis, that are orthogonal to one another. Data may be sequentially accessed (read from or written to) the buffer memory in each of the direction of the first axis, the direction of the second axis, and the direction of the third direction. Second data may written to a given plane of the buffer memory at the same time that first data is read from the same plane of the buffer memory.

A system timer including a divider unit configured to fractionally divide a first clock signal and output a second clock signal having an asymmetric duty ratio and an interrupt generation unit configured to count a cycle of the second clock signal and output an interrupt signal according to the count.
