SK hynix Inc. (Korean: 에스케이하이닉스 주식회사) is a South Korean supplier of dynamic random-access memory (DRAM) chips and flash memory chips. Hynix is the world's second-largest memory chipmaker (after Samsung Electronics)[2] and the world's sixth largest semiconductor company.[3] Founded as Hyundai Electronic Industrial Co., Ltd. in 1983[4] and known as Hyundai Electronics, the company has manufacturing sites in Korea, the United States, mainland China[5] and Taiwan. In 2012, when SK Telecom became its major shareholder, Hynix merged with SK Group[4] (the third largest conglomerate in South Korea at the time).

The company's major customers include Microsoft, Apple,[6] Asus, Dell, MSI, HP Inc., and Hewlett Packard Enterprise (formerly Hewlett-Packard).[2] Other products that use Hynix memory include DVD players, cellular phones, set-top boxes, personal digital assistants, networking equipment, and hard disk drives.[7]
