Abstract:
1. A method of communication to a semiconductor device, comprising: transmitting a sampling clock signal from a first semiconductor device to a second semiconductor device; transmitting plural training signals from the first semiconductor device to the second semiconductor device while transmitting of the sampling clock signal, the plural training signals being sent sequentially to the second semiconductor device, each training signal having a phase with respect to the sampling clock signal, phases of at least some of the training signals with respect to the sampling clock signal being adjusted to be different from each other; receiving first information from the second semiconductor device over a first signal line, the first signal line being separate from a data bus connected between the first semiconductor device and the second semiconductor device; and transmitting a data signal over the data bus while transmitting the sampling clock signal, the data signal being sent at a timing with respect to the sampling clock signal responsive to the received first information.
