About MetaRAM
The MetaRAM technology allows the use of mainstream lower cost DRAM components in the manufacture of the next generation high density DIMMs, without increasing the number of memory ranks or the load on the CPU. The MetaSDRAM chipset consists of flow controllers and an access manager which sit between the memory controller and the DRAM. It enables up to four times more mainstream DRAMs to be integrated into the DIMM without the need for any system level hardware or software changes. The chipset makes multiple DRAMs look like a larger capacity DRAM to the memory controller resulting in high capacity memory modules that circumvent the normal limitations of the memory controller.
