Buffered memory module with implicit to explicit memory command expansion

Abstract

Method and apparatus for use with buffered memory modules are included among the embodiments. In exemplary systems, the memory module has a buffer that receives memory commands and data, and then presents those commands and data to physical memory devices through a separate interface. The buffer has the capability to accept an implicit memory command, i.e., a command that does not contain a fully-formed memory device command, but instead instructs the memory module buffer to form one or more fully-formed memory device commands to perform memory operations. Substantial memory channel bandwidth can be saved, for instance, with a command that instructs a memory module to clear a region of memory or copy a region to a second area in memory. Other embodiments are described and claimed.
