Signal transmission circuit and signal transmission method |
摘要 |
A main bus and a plurality of sub buses constitute a hierarchical bus. A signal transmission circuit is connected between the main bus and each of the plurality of sub buses. The main bus and the plurality of sub buses are precharged to a predetermined potential. The signal transmission circuit discharges a corresponding sub bus or causes the potential of the sub bus to be maintained in accordance with the potential of the main bus when a first enable signal is at a first logic level. The signal transmission circuit causes the potential of a corresponding sub bus to be maintained when a first enable signal is at a second logic level. The signal transmission circuit discharges the main bus or causes the potential of the main bus to be maintained in accordance with the potential of a corresponding sub bus when a second enable signal is at a first logic level. The signal transmission circuit causes the potential of the main bus to be maintained when a second enable signal is at a second logic level.
