Abstract

A communications method is described in which two memory modules receive data and commands from a controller module via a common data and command bus. The memory modules contain active line terminations. By a second chip select input, one of the memory modules can monitor the write commands that pass from the controller module to the other memory module, and thus activate the line terminal in the monitoring memory module.
