    摘要: 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.

    摘要: Some embodiments of the invention enable debugging functionality for memory devices residing on a memory module that are buffered from the memory bus by a buffer chip. Some embodiments map connector signals from a tester coupled to the high speed interface between the buffer chip and the memory bus to an interface between the buffer chip and the memory devices. During test mode, some embodiments bypass the normal operational circuitry of the buffer chip and provide a direct connection to the memory devices. Other embodiments use the existing architecture of the buffer chip to convert high speed pins into low speed pins and map them to pins that are connected to the memory devices. Other embodiments are described in the claims.
