Clock buffer enables novel memory modules

Zero-Buffer DDR (ZB-DDR) technology is a novel technique for unbuffered memory modules developed jointly by memory supplier OCZ Technology Group with Inphi Corp.

Using discreet zero-delay clock buffers, ZB-DDR technology combines the robustness of server class memory with the low latency of unbuffered modules, resulting in better data integrity, lower noise and lower susceptibility to interference over a wider frequency spectrum while still remaining fully compatible with all current motherboards.

"At the module level, only with a clock buffer delay at 50ps or less, is it possible to generate loss-less memory clock signals that are not subjected to the impact of noise found in a distributed clock tree", said Dr Michael Schuette, Director of Technology Development at OCZ Technology.

ZB-DDR technology uses the state of the art Inphi INCU 877 clock buffers with a custom-developed PCB matched to the impedance of the clock buffer.

"We are very pleased to have OCZ as a partner in this pioneering high-tech endeavour", commented Desi Rhoden, Executive Vice President of Inphi Corporation.

"Precision clock signals provided by our clock buffers are the key to signal integrity and minimised error rates".
