Abstract
A memory buffer for an FB-DIMM having a first input/output interface for communicating with a memory controller at a first payload data rate and a second input/output interface for communicating with memory packages at a second payload data rate, wherein a relation of the first payload data rate to the second payload data is greater than 10.
Claims20
A memory buffer for an FB-DIMM comprising:
- a first input/output interface for communicating with a memory controller at a first data rate;
- and
- a second input/output interface for the communication of read/write data with memory packages at a second data rate,
- wherein a relation of the second data rate divided by the first data rate is less than 1/10.
1 more element
An FB-DIMM comprising:
- a plurality of memory packages coupled to a substrate;
- and
- a memory buffer coupled to the substrate, the memory buffer having a first input/output interface for communicating with a memory controller at a first data rate and a second input/output interface for communicating read/write data with the memory packages at a second data rate, wherein the relation of the second data rate divided by the first data rate is less than 1/10.
A method for operating a memory buffer for an FB-DIMM, the method comprising:
- communicating with a memory controller at a first data rate;
- and communicating read/write data with memory packages at a second data rate, wherein a relation of the second data rate divided by the first data rate is less than 1/10.
