Memory modules having integral terminating resistors and computer system boards for use with same

摘要

A memory module for use with a computer system board includes at least one memory chip connected to a bus line conductor and a terminating resistor connected to the bus line conductor. The memory module further includes a connector configured to connect the bus line conductor to bus line of the computer system board. A computer system board includes a bus line including first branch configured to connect to a first memory module and a second branch configured to connect to a second memory module. The computer system board further includes a memory controller coupled to the first and second branches of the bus line at a single pin thereof. In other embodiments, a computer system board includes a bus line having first and second branches. A first switch is operative to selectively couple a first plurality of memory modules to a first branch of a bus line of the system board. A second switch is operative to selectively couple a second plurality of memory modules to the second branch of the bus line. The system board further includes a memory controller connected to the first and second branches of the bus line at a single pin thereof.
