Patent ID: 7577789

Claim:
A system comprising: a. a motherboard including: i. a first electrical receptacle; ii. a first set of signal lines coupled to the first electrical receptacle; iii. a second electrical receptacle; and iv. a second set of signal lines coupled to the second electrical receptacle; and b. at least one of a first logic module and a second logic module; c. the motherboard supporting multiple data-width configurations, including: i. a single-module configuration in which the first logic module is inserted into the first electrical receptacle and the second electrical receptacle lacks the second logic module, wherein the first logic module is coupled, via the first electrical receptacle, to the first and second sets of signal lines and is receiving first data of a first data width transferred to the first electrical receptacle via both the first set of signal lines and the second set of signal lines; and ii. a dual-module configuration in which the first logic module is inserted into the first electrical receptacle and the second logic module is inserted into the second electrical receptacle, wherein the first logic module is coupled, via the first electrical receptacle, to the first set of signal lines and is receiving second data of a second data width narrower than the first data width and transferred to the first electrical receptacle via the first set of signal lines, and wherein the second logic module is coupled, via the second electrical receptacle, to the second set of signal lines and is receiving third data transferred to the second electrical receptacle via the second set of signal lines; wherein in the dual-module configuration the first logic module is decoupled from the second set of signal lines and does not receive data via the second set of signal lines.
