DDR2 MetaSDRAM

MetaSDRAM is a drop-in solution to the persistent gap between processor computing power, which doubles every 18 months – and DRAM capacity, which doubles only every 36 months – a gap that is limiting processor performance. MetaSDRAM technology has accelerated DRAM densities by 2 to 4 years.

MetaSDRAM Technology
MetaRAM’s DDR2 MetaSDRAM is a new memory technology that doubles or quadruples the amount of mainstream DDR2 SDRAMs that can be integrated into existing R-DIMMs without the need for any system hardware or software changes. The MetaSDRAM chipset makes multiple DDR2 SDRAMs look like a larger capacity DDR2 SDRAM to the memory controller. The result is a “stealth” high-capacity memory that circumvents the normal limitations set by the memory controller.

MetaSDRAM Chipset
The DDR2 MetaSDRAM Chipset contains two types of ASICs designed and manufactured by MetaRAM: the Access Manager, responsible for address and command management, and the Flow Controller, responsible for data management. Each MetaSDRAM chipset is optimized for low power and high performance. DDR2 MetaSDRAM Chipsets come in 8GB or 16GB kit versions and are capable of running at speeds up to 667MT/s.

MetaSDRAM R-DIMM
A MetaSDRAM R-DIMM combines a MetaSDRAM chipset with 72 or 144 mainstream 1Gb SDRAMs to provide an 8GB or 16GB DIMM that is compatible with industry standards and existing platforms.

Memory Drivers
MetaSDRAM R-DIMMs are designed for high performance rack-mount servers and workstations that run compute-intensive applications such as CAD/EDA simulations, database transaction processing (OLTP), digital content creation, and virtualization.  These and other heavy workload applications are the backbone of industries like aerospace, automotive, financial services, animation, oil and gas exploration, and semiconductor design and simulation. Virtualization software and server consolidation is an emerging technology that IT managers are pursuing in order to save energy and costs. The number of virtual machines that can be run on one processor is exploding as the number of cores, processing power, and frequencies on a processor grow in relation to Moore’s law. At the same time, the number of loads which can be put on the memory bus is falling as speeds increase from DDR2-533 to DDR3-1600 and beyond. MetaSDRAM is the key to solving these challenges and others.
