Abstract:
1. A system, comprising: a memory including a data signal line and a data synchronization signal line; and an information processing device which performs a data communication to and from the memory via the data signal line, wherein the memory includes a setting module configured to store mode information, wherein the mode information determines whether the data signal line is set to be a data signal line for common input/output use in a first mode, a data signal line for output-only use in a second mode, or a data signal line for input-only use in a third mode, and wherein the mode information further determines whether the data synchronization signal line is set to be a data synchronization signal line for common input/output use in the first mode, a data synchronization signal line for output only use in the second mode, or a data synchronization signal line for input only use in the third mode; wherein the information processing device provides a data signal line set command the mode information, wherein the data signal line set command instructs the memory to load the mode information into the setting module for specifying one of the first mode, the second mode, and the third mode corresponding to a type of the data communication before performing the data communication; and wherein the memory sets the data signal line and the data synchronization signal line into the one of the first mode, the second mode, and the third mode based at least in part on the mode information stored in the setting module, and performs the data communication based on the set of commands by using the data signal line set in the one of the first mode, the second mode, and the third mode.
