Memory module having on-package or on-module termination

摘要

A memory module adapted for installation in an open memory socket on a mainboard of a computer. The memory module includes a substrate with an edge connector comprising pins along an edge of the substrate, and at least one memory package mounted to the substrate and containing a memory die electrically connected to input/output leads located along the perimeter of the memory package and through which data signals are transmitted to and from the memory die. Data signal lines electrically connect a plurality of the input/output leads of the memory package to a plurality of the pins of the edge connector. Termination resistors individually electrically connect each of the data signal lines to ground, a supply voltage, or a reference voltage of the memory package so as to reduce noise and signal reflections through the data signal lines.
