Chung Ju-yung
Chung Ju-yung or Jung Joo-young (; 25 November 1915 – 21 March 2001) was a South Korean entrepreneur and the founder of Hyundai Group, Hyundai Group, one of the largest chaebols in South Korea. Raised as the eldest son of a poor Korean farme ...

. 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

However, LG and Hyundai were pressured by the government to merge, as both companies faced significant losses during the semiconductor recession of early 1996.
