8Gb DDR3 components double memory per chip

The world's first 8Gb (Gigabit) DDR3 components with a single chip-select developed by Hong Kong-based I'M Intelligent Memory boast a twofold increase in the amount of memory per chip compared to other DDR3 DRAM devices on the market. Based on these new 8Gb components, I'M is also introducing the first 16GB (Gigabyte) DDR3 UDIMM and SO-DIMM memory modules with optional ECC error-correction.

The JEDEC specification JESD79-3 has always allowed an 8Gb density for DDR3 memory devices. While most DRAM manufactures are waiting for a 2x nm process to fit such high memory capacity into a single DRAM IC package, I'M has developed its own way to manufacture 8Gb DDR3 components with single chip-select utilising existing 30nm manufacturing technologies.

The I'M 8Gb components are 100 per cent compatible with the JEDEC standard pinout, timing, and row/column/bank addressing, providing the simplest path to higher density DDR3 upgrades. These devices allow for a new level of memory capacity without altering existing board-layouts or designs.

I'M memory modules

Orderable devices include a x8 (1Gx8) configuration in FBGA 78 ball package, a x16 (512Mx16) type in FBGA 96 ball package as well as a x32 (256Mx32) configuration in FBGA 136 ball package. In addition, I'M offers DDR3L low-voltage (1.35V) versions of these devices. The products are available in commercial and industrial temperature ranges.

Based on their new 8Gb device, I'M releases the very first 16GB DDR3 240 Pin unbuffered DIMMs (UDIMMs) and 204 Pin SO-DIMMs to the market. These new high-capacity memory modules are also available with a 72bit width for ECC error correction.

The 8Gb components and 16GB modules have been verified to be compatible with processors and microcontrollers from AMD, Cavium, Freescale, Tilera, and many others.

Intel currently supports 8Gb components and 16GB modules only on their Atom C2000 series (Codename 'Avoton') and Atom E3800 (Baytrail-I) processor series. New BIOS versions for these platforms are required to use the memory and are available now.

For most standard Intel processors that are used in desktop PCs, laptops, or servers, Intel is not yet supporting the new high capacity memories. According to Intel, "it is not POR" (Plan Of Record) for them to analyse the possibility to support them, unless they can see a demand from the market for these new memory products.
