A low-power DDR3 memory buffer for LRDIMM applications increases memory capacity at higher speeds. The MB3518 buffer from Integrated Device Technology, Inc. (IDT) runs at 1.5 V or 1.35 V and operates at speeds up to 1866 megatransfers per second (MT/s) with two LRDIMMs in a channel.
The device offers 512 GB density, assuming quad-rank LRDIMMs at 32 GB. The capacity can be doubled to more than 1 TB using eight-rank 64 GB LRDIMMs, expected to launch in 2013. Additionally, the memory buffer features proprietary debug and validation features, including per-pin, on-die oscilloscope capability and built-in logic analyzer capture to expedite the development, validation, and test of fully buffered DIMM topologies.
Supports DDR3-800, 1066, 1333, 1600, and DDR3-1866
