MEMORY MODULE WITH PROGRAMMABLE COMMAND BUFFER

Abstract:

A memory module includes a plurality of memory integrated circuit (IC) packages to store data and a command buffer IC to buffer one or more memory commands destined for the memory IC packages. The command buffer IC includes a first interface circuit and one or more second interface circuits. The first interface circuit receives the one or more memory commands. The one or more second interface circuits output a pre-programmed command sequence to one or more devices separate from the command buffer IC, the pre-programmed command sequence output in response to the one or more memory commands matching a pre-programmed reference command pattern.
