IDT ( www.idt.com , Country Manager for Korea: Sang-Yup Lee), an analog-digital company leading the core semiconductor solutions market, announced today that it is introducing the industry's first low-power DDR3 memory buffer capable of operating at a transfer speed of up to 1,866 megatransfers per second (MT/s).

This newly introduced device enhances the maximum data transfer speeds of DDR3 LRDIMM (Load-reduced Dual-inline Memory Module), enabling system manufacturers to benefit from higher speeds and increased memory capacity, thereby solidifying IDT's leading position in memory interface solutions. IDT's memory buffers are a core component of high-performance memory subsystems used in server, workstation, and storage applications.

The MB3518 is a low-power DDR3 memory buffer capable of operating at speeds up to 1866 MT/s using two LRDIMMs in a single channel. When using quad-class 32GB LRDIMMs, it provides 512GB of capacity and an output of 1866 MT/s in typical servers; this performance can be doubled to over 1TB when using 64GB class 8 LRDIMMs, which are scheduled for release in 2013. Accordingly, relative density is improved fourfold compared to standard RDIMMs (Registered Dual-inline Memory Modules) based on the industry's highest speed class, enabling computing systems to support more memory and improve application performance. This memory buffer operates at 1.5V or 1.35V, allowing for the lowest power consumption in the industry without compromising performance. These features provide end users with significant operating cost savings in terms of power and cooling.

Mario Montana, Vice President and General Manager of IDT’s Enterprise Computing Business Unit, stated, “As a leader in memory interface solutions, IDT is pushing the limits of LRDIMM performance. By focusing on low power and high performance, IDT’s customers will be able to develop energy-efficient solutions that realize the benefits of enhanced speed while lowering data center operating costs and reducing their carbon footprint. From a systems perspective, IDT’s extensive portfolio of interface and interconnect products offers a competitive value proposition to diverse customers looking to launch cutting-edge enterprise servers and storage equipment.”

Robert Feurle, Vice President of DRAM Marketing at Micron Technology, Inc. (NASDAQ: MU), stated, “Micron is focused on supplying LRDIMMs that meet the requirements of customers in the high-performance computing (HPC), data center, and cloud computing sectors by increasing performance while lowering power. We are pleased to collaborate with IDT to realize next-generation LRDIMM products.”

IDT Memory Buffer accelerates the development, verification, and testing of full-buffered DIMM topologies based on proprietary debug and verification specifications, including on-die oscilloscope capabilities per pin and built-in logic analyzer capture. These specifications are particularly important for the memory buffer-DRAM interface of LRDIMM modules because the interface is completely isolated from the host controller and automated testers. The IDT memory buffer complies with the strict specifications set by JEDEC (Joint Electronic Device Engineering Council).

Price and supply
IDT’s MB3518 and MB3516 are currently being sampled to selected customers and are supplied in 588-pin FCBGA packages, with both led and non-lidded options.
