OCZ and Inphi introduce Zero-Buffer DDR
OCZ in a joint effort with Inphi nnounced the release of Zero-Buffer DDR (ZB-DDR) technology for unbuffered memory modules.
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, the firms said.
"At the module level, only with a clock buffer delay at 50 picoseconds 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.
ZB-DDR technology uses Inphis INCU 877 clock buffers with a custom-developed PCB matched to the impedance of the clock buffer.
