SK Hynix

SK Hynix is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand SK Hynix rather than just read about it. In short: SK Hynix Inc. (Korean: 에스케이하이닉스 주식회사), stylized SK hynix, is a South Korean semiconductor company that manufactures dynamic random-access memory (DRAM) chips and flash memory chips.

Key takeaways

  • SK Hynix belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect SK Hynix to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of SK Hynix from memory before moving on to harder problems.

Reference excerpt

SK Hynix Inc. (Korean: 에스케이하이닉스 주식회사), stylized SK hynix, is a South Korean semiconductor company that manufactures dynamic random-access memory (DRAM) chips and flash memory chips. SK Hynix is one of the world's largest semiconductor vendors, and along with Samsung Electronics and Micron is one of the "Big Three" memory manufacturers. Founded in 1983 as Hyundai Electronics, SK Hynix was integrated into the SK Group in 2012 following a series of mergers, acquisitions, and restructuring efforts. After being incorporated into the SK Group, SK Hynix became a major affiliate alongside SK Innovation and SK Telecom. The company's major customers include Nvidia, Microsoft, Apple, Asus, Dell, MSI, HP Inc., and Hewlett Packard Enterprise (formerly Hewlett-Packard). Other products that use Hynix memory include DVD players, cellular phones, set-top boxes, personal digital assistants, networking equipment, and hard disk drives.

History

Beginning

Hyundai Electronics

Hyundai Electronics was founded in 1983 by Chung Ju-yung, the founder of Hyundai Group. In the early 1980s, Chung recognized the growing importance of electronics in the automobile industry, one of Hyundai's primary business areas. He saw the potential for Hyundai to expand beyond its core operations in automobiles, shipbuilding, and heavy industries and wanted to establish a presence in the promising electronics industry. The company's primary focus was on semiconductor production and industrial electronics. Hyundai had to pay a very high entry price to set up an efficient production system and to stabilize the yield rate compared to its rival Samsung, who at least had prior experience in semiconductor manufacturing. Hyundai's decision to produce SRAMs was later proven to be a mistake, as the technological sophistication of SRAMs made it difficult for Hyundai to achieve a satisfactory yield rate. In 1985, Hyundai altered its strategy for DRAM manufacturing by subcontracting from foreign firms and importing their chip designs, as it had lost time developing its own chips. Hyundai's DRAM chip, produced by importing Vitelic Corporation's design and technology, again failed in mass production due to a low yield rate. Hyundai's approach to manufacturing memory chips as a foundry for foreign firms under OEM agreements was successful. The OEM agreements between General Instruments and Texas Instruments were helpful to Hyundai, which was facing technological and financial difficulties. By 1992, Hyundai had become the world's ninth DRAM manufacturer, and by 1995, it ranked among the world's top 20 semiconductor manufacturing companies. In 1996, Hyundai acquired Maxtor, a U.S.-based disk-drive manufacturer.

LG Semicon

GoldStar, which later became LG Electronics, entered the semiconductor business by acquiring a small company from Taihan Electric Wire in 1979. The company was subsequently renamed GoldStar Semiconductor. LG Semicon was established as Goldstar Electron in 1983 by merging the semiconductor operations of Goldstar Electronics and Goldstar Semiconductors. In 1990, Goldstar Electron commenced operations at Cheongju Plant I, followed by the completion of Cheongju Plant II in 1994. The company underwent a name change to LG Semicon in 1995. LG Semicon operated from three sites, including Seoul, Cheongju, and Gumi.

Merger During the 1997 Asian financial crisis, the South Korean government initiated the restructuring of the nation's five major conglomerates, including their semiconductor businesses. Among five chaebols, Samsung, LG, and Hyundai were engaged in the semiconductor business. Samsung was exempt from the restructuring due to its competitive position in the global market. However, LG and Hyundai were pressured by the government to merge, as both companies faced significant losses during the semiconductor recession of early 1996. In 1998, Hyundai Electronics acquired LG Semicon for US$2.1 billion, positioning itself in direct competition with Micron Technology. Subsequently, LG Semicon was rebranded as Hyundai Semiconductor and later merged with Hyundai Electronics.

Hynix

Although the South Korean government aimed to merge the two companies to alleviate the supply glut in the global market, competition in the semiconductor industry had intensified. Hyundai faced near collapse during the chip industry's downturn in 2001, when global memory chip prices dropped by 80 percent, resulting in a 5 trillion won annual loss for the company. Creditor banks, many of them under government control at the time, intervened to provide assistance. In 2001, Hyundai Electronics rebranded as Hynix Semiconductor, a portmanteau of "high" and "electronics". Alongside this change, Hynix began selling or spinning off business units to recover from a cash squeeze. Hynix separated several business units, including Hyundai Curitel, a mobile phone manufacturer; Hyundai SysComm, a CDMA mobile communication chip maker; Hyundai Autonet, a car navigation system producer; ImageQuest, a flat panel display company; and its TFT-LCD unit, among others. The divestiture was part of a bailout plan requested by the major creditor, Korea Development Bank, to provide fresh funds to the insolvent semiconductor maker. In 2003, Hyundai Group affiliates, including Hyundai Merchant Marine, Hyundai Heavy Industries, Hyundai Elevator, and Chung Mong-hun, the chairman of Hyundai Asan, consented to forfeit their voting rights and sell their stakes in Hynix. Hynix was then formally spun-off from the Hyundai Group in August 2003.

Worked examples

Example 1 — a first encounter with SK Hynix

Start with the simplest possible case. Write down what SK Hynix claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to SK Hynix before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about SK Hynix ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of SK Hynix

In research
SK Hynix appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses SK Hynix in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
SK Hynix is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1996 initial public offerings, Companies based in Gyeonggi Province, Companies in the KOSPI 200, so understanding it makes those chapters shorter.
In everyday life
Look for SK Hynix outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
