|SK Hynix: Foreign Investors Buy SK Hynix, Sell Samsung ElectronicsSK Hynix Preferred to Samsung ElectronicsForeign investors show a different investment strategy toward SK Hynix and Samsung Electronics. They have been buying SK Hynix shares but selling Samsung Electronics after the Lunar New Year holiday. Market experts believe that this is largely due to the adjustment over a lockup period before Samsung Electronics' stock split.According to the Korea Exchange on Feb. 21, SK Hynix closed at 76,900 won (US$71.47) on the same day, up 1.85 percent from the previous trading day. SK Hynix received an adjustment by 1.42 percent and 1.31 percent, respectively, for two days from the 19th, the first trading day after the Lunar New Year holiday, but succeeded in a rally on the 21st. On the other hand, the price of Samsung Electronics shares has been falling for three trading days in a row after the 19th. The company lost 0.25 percent to close at 2,364,000 won (US$2,197).Overseas investors bought a net 66.88 billion won (US$62.05 million) worth of SK Hynix shares after the 19th. They have been net buying for 10 trading days in a row from the 6th to the 21st. By contrast, foreign investors are net selling Samsung Electronics shares for three consecutive trading days. They shed 164.6 billion won (US$152.45 million) worth of Samsung Electronics shares after the Lunar New Year holiday.The stock industry expects to see a boom in the semiconductor market and a rise in material prices. This is because semiconductor material producers are forecast to show a good performance due to an increase in both shipments and prices this year. It will also lead to the limitation of DRAM supplies, which is the upstream industry, boosting the prices.However, Samsung Electronics has a variable caused by the stock split aside from the medium-term forecasts for the semiconductor industry. The stock split is the fact that already publicly announced in the market. It can be positive in share prices in the short term but there is no change in corporate values, according to recent analyses.News›MoneyBusinessKorea|

|SK Hynix: SK Hynix Announces SSDs with 72-Layer 3D NAND ICs, Own ControllersSK Hynix this week has said it has completed development of its enterprise-grade SSDs based on its 512 Gb 72-layer 3D TLC NAND chips as well as its own controllers and firmware. The drives will be available with SATA and PCIe interfaces and will target various applications. Select clients of SK Hynix have already received samples of its eSSDs.SK Hynix's SATA SSDs are based on the company's 72-layer 3D NAND 512 Gb chips, and are designed to offer up to 4 TB of raw NAND flash memory. These drives are rated to support sequential read and write speeds of up to 560 MB/s and 515 MB/s respectively. When it comes to random performance, these drives are capable of up to 98K random read IOPS and up to 32K random write IOPS (but SK Hynix does not disclose queue depth and other factors).As for SK Hynix's PCIe-based drives, they come in an M.2 form-factor and offer capacities of 1 TB or higher. The manufacturer declares sequential read performance of up to 2.7 GB/s, sequential write performance of up to 1.1 GB/s, random read performance of up to 230K IOPS as well as random write performance of up to 35K IOPS. SK Hynix does not disclose feature set, but based on their images we can expect them to offer power loss protection.SK Hynix's Enterprise SSDs at a Glance 7mm SATAM.2 NVMePCIe 3.0ControllerProprietary SK Hynix ControllersNAND Flash72-Layer 3D TLC NANDCapacityUp to 3840 GBOver 1TBSequential Read560 MB/s2700 MB/sSequential Write515 MB/s1100 MB/sRandom Read IOPS98K230KRandom Write IOPS32K35KPseudo-SLC CachingSupported (?)DRAM BufferYes, capacity unknownSK Hynix began production of 72-layer 3D NAND (3D-V4) 512 Gb chips, we believe, in the fourth quarter of 2017, but did not make any formal announcements on the matter. The new chips feature the highest bit density that SK Hynix can offer today and they also offer higher performance compared to predecessors because of a 13.5 MB block size, a reduced tPROG page programming time, and a 667-800 MT/s Toggle 2.0 interface (the manufacturer does not disclose exact data rate of its interface).SK Hynix does not disclose any details about its datacenter-grade SSD controllers, but it is likely that they were developed by engineers from LAMD, a company that SK Hynix acquired back in 2012. Keeping in mind that we are dealing with 3D TLC NAND-based SSDs, it is highly likely that the controllers support an ECC technology based on an LDPC algorithm.SK Hynix did not disclose when it expects to ship its enterprise drives to customers, but if its product catalogue is to be believed, the high-capacity SATA drives will be available commercially in the third quarter. Meanwhile, since we are dealing with enterprise SSDs, existing clients of SK Hynix will adopt them when they are satisfied with their real-world performance, reliability, endurance and other factors, so they may start using them ahead of Q3, or later.Related ReadingSK Hynix Launches 72-Layer 256 Gb 3D TLC NAND with Increased PerformanceSK Hynix Lays Out Plans for 2017: 10nm-Class DRAM, 72-Layer 3D NANDToshiba Samples 64-Layer 512 Gb BiCS 3D NAND, Announces 1 TB BGA SSDMicron 2017 Roadmap Detailed: 64-layer 3D NAND, GDDR6 Getting Closer, & CEO RetiringAnandTech|

|SK Hynix: SK Hynix's Product Catalog Lists 16 Gb DDR4 Chips, Opens Doors to 256 GB DIMMsSK Hynix has recently added single-die DDR4 memory chips featuring 16 Gb capacity to its product catalog. The benefit of the increase in single-die capacity is two fold: not only will the new components enable the company to build high-capacity memory modules using fewer chips, but also it will enable SK Hynix and its partners to build 256 GB DDR4 memory modules for ultra-high-end servers.16 Gb DRAM chips per se are not exactly a breakthrough. Memory makers, including SK Hynix, already build high-capacity DRAM components by stacking two or four 8 Gb memory dies vertically using TSVs to get 16 Gb and 32 Gb components, then use such chips to build memory modules featuring 64 GB and 128 GB density. Stacking makes organization of DIMMs very complex: in the case of a 64 GB module we are dealing with a quad-ranked DIMM (featuring two physical and two logical ranks), whereas a 128 GB module is octal ranked (featuring two physical ranks and four logical ranks). LRDIMMs have a relatively high latency in general (because they use additional buffers), meanwhile complexity of 64 GB/128 GB LRDIMM architecture forces module makers to increase them even further (to CL20/CL22 for DDR4-2400/DDR4-2666 speed bins).By contrast, SK Hynix has managed to develop single-die 16 Gb DDR4 components. Such ICs enable producers to build client memory modules or subsystems with a fewer number of chips, lowering power consumption, and allows server-class DIMMs with densities of up to 256 GB. When it comes to servers, the 16 Gb DDR4 components will allow to build dual-ranked 64 GB modules, quad-ranked 128 GB LRDIMMs and octal-ranked 256 GB LRDIMMs.Do not expect the 256 GB modules to show up tomorrow, but the importance of ultra-high-density LRDIMMs is hard to overestimate. For example, if the microcode is adjusted to allow it, a single socket Xeon Scalable platform featuring an -M suffixed processors with 12 total memory slots could potentially support 3 TB of six-channel memory. Meanwhile, an AMD EPYC-based system can currently support 2 TB of eight-channel memory per CPU socket, and these modules could help support double that. For in-memory applications like huge databases, the more DRAM they can get the better. Undoubtedly, 128 GB and 256 GB memory modules will come at a price. For example, Crucial sells its 128 GB DDR4-LRDIMM for $3999.99 in retail, so a 2X capacity module would cost considerably higher.SK Hynix's 16 Gb DDR4 chips are organized as 1Gx16 and 2Gx8 and supplied in FBGA96 and FBGA78 packages, respectively. At present, 16 Gb memory components are rated to operate in DDR4-2133 CL15 and DDR4-2400 CL17 modes at 1.2 Volts. Sometimes in the third quarter SK Hynix plans to add DDR4-2666 CL19 to the lineup. SK Hynix does not disclose which manufacturing technology it uses to make its 16 Gb chips, but it is logical to expect that the company uses a fabrication process with minimal feature sizes and high yields to make large dies.General Specifications of SK Hynix's 16 Gb ChipsPart NumberTransfer RateLatencyOrg.Pkg.VDDAvailabilityH5ANAG6NAMR-TFC2133 MT/s15-15-151Gx16FBGA961.2 VNowH5ANAG6NAMR-UHC2400 MT/s17-17-17H5ANAG6NCMR-UHC2400 MT/s17-17-17Q3 2018H5ANAG6NCMR-VKC2666 MT/s19-19-19H5ANAG8NAMR-TFC2133 MT/s15-15-152Gx8FBGA78NowH5ANAG8NAMR-UHC2400 MT/s17-17-17H5ANAG8NCMR-UHC2400 MT/s17-17-17Q3 2018H5ANAG8NCMR-VKC2666 MT/s19-19-19Keep in mind that it will take quite a while for server makers to validate 16 Gb chips and 2Hi/4Hi stacks based on them, so do not expect 256 GB modules to hit today's servers shortly from now. In the meantime, 16 Gb DDR4 chips will enable makers of SO-DIMMs to build single-sided 16 GB DDR4 SO-DIMM modules. This will also allow thin laptops (that do not use modules, but rely on commodity memory) to install 16 GB of DRAM using eight chips. For any user wondering why most 13-inch notebooks do not want to use 16 GB of DRAM in all but the high-end specification, these chips should enable a nicer ecosystem for higher memory capacity small notebooks.Related ReadingMega Memory: Crucial Ships 128 GB DDR4-2666 Modules for Servers at $3999 per UnitIntel Unveils the Xeon Scalable Processor Family: Skylake-SP in Bronze, Silver, Gold and PlatinumCrucial Announces DDR4-2666 DIMMs for Upcoming Server PlatformsSizing Up Servers: Intel's Skylake-SP Xeon versus AMD's EPYC 7000 - The Server CPU Battle of the Decade?Dual Xeon Scalable Overclocking: ASUS WS C621E 'Sage' Workstation Motherboard AnnouncedDDR4 Haswell-E Scaling Review: 2133 to 3200 with G.Skill, Corsair, ADATA and CrucialASRock Rack Announces EP2C612D24 and 4L: Dual Socket Haswell-EP with 24 DDR4 SlotsAnandTech|
