“Data bus” refers to a communication bus used to exchange one or more of data bits between two electronic circuits, components, chips, die, and/or systems. A data bus may include one or more signal lines. A sender, such as a controller, may send data signals over one or more control lines of the data bus in parallel or in series. Examples data buses may include 8-bit buses having 8 control lines (also called data lines, if they only carry data signals), 16-bit buses having 16 control lines, 32-bit buses having 32 control lines, 64-bit buses having 64 control lines, and the like.
In one embodiment, a single data bus may be shared by a plurality of components, such as memory die. When multiple chips or memory die share a data bus, that data may be accessed or transferred by a single memory die or by all the memory die in parallel based on signals on a chip enable control line.
A data bus may operate, and be configured, according to an industry standard or based on a proprietary protocol and design. Multiple control line of a data bus may be used in parallel and may latch data into latches of a destination component according to a clocking signal, data strobe signal (“DQS”), or clock, such as strobe signal.
