lpddr2 Samsung shrinks its LPDDR2 products to 2Xnm, doubles the capacity

DDR4 will potentially arrive in the server space come next year, yet most mobile devices are still using DDR or DDR2 memory, with only a handful shipping with DDR3 memory. Samsung has announced that it has managed to improve things in several ways by shrinking its LPDDR2 memory to 2Xnm.

DDR4 will potentially arrive in the server space come next year, yet most mobile devices are still using DDR or DDR2 memory, with only a handful shipping with DDR3 memory. Samsung has announced that it has managed to improve things in several ways by shrinking its LPDDR2 memory to 2Xnm.

For starters, the die shrink allows Samsung to produce more affordable 4Gbit memory dies than what the company could using its 3Xnm technology, something that in the long run should make for more affordable devices. However, the initial benefit is that Samsung can now package four dies in a single memory package for 2GB chips, twice that of what was commonly available using 3Xnm manufacturing technology.

Add to this the fact that Samsung has managed to shave off 20 percent of the height of the actual memory chips – down to a mere 0.8mm – and you have an ideal candidate for PoP or Package on Package type usage where the DRAM sits on top of the ARM SoC, a common thing in many smartphones for example. Considering that the market is already moving towards 2GB of RAM in smartphones, this clearly the way forward for any DRAM manufacturer that wants to stay on top of the competition.

Samsung's new LPDDR2 memory will be available in speeds of up to 1,066MHz, but it said to be more power efficient than its 30nm siblings at the same speed. The new DRAM chips went into mass production last month and should be available to Samsung's partners shortly. The press release also quoted expected market share numbers of LPDDR2 by IHS iSupply who claims that about 13 percent of the market of mobile devices will use LPDDR2 this year, with 49 percent next year and 63 percent by 2014.
