DIMM memory modules with a capacity of 128 GB will only be released in 2015, and 64 GB models are pretty rare too. However, it's a lot easier to release high-capacity RDIMM ones, especially when you're the one who's making the chips, as is the case with Samsung.

In case you didn't know, Samsung is one of the world's major suppliers of semiconductors. Sure, Intel may be the most famous CPU maker, but Samsung has its own range (ARM-based) and is a major name on the RAM and NAND Flash markets as well.

It is the random access memory technology front where the group has just made its move. Samsung has formally released two products. Technically, it's one product and a second one based on it, but eh, details.

The 8 Gigabit DDR4 memory chip

This is the primary point of interest here. The chip has a storage space of 8 Gb, which is basically the same as one gigabyte.

The chip is built on the 20nm manufacturing process, which ensures a high efficiency and lower cost of manufacture than other nodes. Which, in turn, should boil down to lower price for the chip itself and, in turn, for the module of 32 GB.

Since the new memory is made of enterprise and business products, you can be sure that some clients will order the chips in bulk and make system boards and memory PCBs themselves.

The 32 GB DDR4 module

The RDIMM has a total capacity of 32 GB and a data rate of 2,400 megabits per second (Mbps) per pin, which is 29% faster than the normal performance of DDR3 (1,866 Mbps).

Admittedly, DDR3 often works at 1,600 Mbps / MHz, but in enterprise applications it's hard to find anything slower than 1,866 Mbps, so the latter makes for a more accurate comparison.

Either way, with DDR4 also providing a major decrease in power requirements, the benefits of upgrading to the new RAM easily offset the disadvantages.

The RDIMM form factor should be compatible with all servers out there and the larger installations based on them, like data centers and clouds.

Availability and pricing

The memory should already be available for sale, but prices will be subject to order size and further negotiations. There are 4 Gb and 6 Gb chips as well. However, larger-capacity products like 128 GB modules will take a while to make. Not too long though, since Samsung already has 3D through silicon technology (TSV).
