context_page_description: This is a list of Korean inventions and discoveries; Koreans have made contributions to science and technology from ancient to modern times. In the present, South Korea plays an active role in the ongoing Digital Revolution, with one of the largest electronics industries and most innovative economies in the world.
context_section_description: Metal-oxide-semiconductor field-effect transistor (MOSFET)
  In 1959, Dawon Kahng and Mohamed Atalla at Bell Labs invented the metal-oxide-semiconductor field-effect transistor (MOSFET), a semiconductor that is the basic element in most of today's electronic equipment. It is the basic building block of the Digital Revolution, and the most widely manufactured device in history.
  Floating-gate MOSFET (FGMOS)
  In 1967, Dawon Kahng and Simon Min Sze invented the floating-gate MOSFET, which provides the foundation for many forms of semiconductor memory devices.
  Synchronous dynamic random-access memory (SDRAM)
  The first commercial synchronous dynamic random-access memory (SDRAM) was the Samsung KM48SL2000 memory chip. It was introduced by Samsung Electronics in 1992, and mass-produced in 1993.
  Double-data rate SDRAM (DDR SDRAM)
  First demonstrated by Samsung in 1997. Samsung released the first commercial DDR SDRAM chip in June 1998.
  MP3 player
  The world's first commercially available MP3 player, the MPMan, was launched by SaeHan Information Systems in 1997.
  Graphics DDR SDRAM (GDDR SDRAM)
  GDDR was initially known as DDR SGRAM (double data-rate synchronous graphics RAM). It was commercially introduced by Samsung Electronics in 1998.
  MP3 phone
  The first mobile phone to support MP3 playback, the SPH-M2100, was released by Samsung in 1999.
  TV phone
  The world's first TV phone, the SCH-M220, was developed by Samsung in 1999.
  Tablet computer
  The first commercially available tablet computer, the GRiDPad, was manufactured by Samsung in 1989 after it absorbed GRiD Systems Corporation in 1988. The GRiDPad was modified from the Samsung PenMaster, which was never commercially released.
  Watch phone
  The world's first watch phone, the SPH-WP10, was released by Samsung in 1999.
  Curved display smartphone
  The world's first curved display smartphone, the Samsung Galaxy Round, was released by Samsung on 10 October 2013.
  Solar-powered cell phone
  The world's first solar-powered cell phone, the Samsung E1107, was released by Samsung in 2009.
  EyeCan
  Samsung developed the first eye tracking mouse that doesn't require users to wear special equipment, called the EyeCan, in 2012.
  Touchscreen phone
  The LG Prada is the world's first completely touchscreen mobile phone, and also the first mobile phone with a capacitive touchscreen.
  5G smartphone
  Samsung released the world's first 5G smartphone, the Galaxy S10 5G, in 2019.
  LTE mobile phone
  Samsung released the world's first LTE mobile phone, the SCH-r900, in 2010, and the world's first LTE smartphone, the Samsung Galaxy Indulge, in 2011.
  Retina display
  Apple's "Retina" display was invented by LG and bought by Apple.
  3D hologram
  The world's first 360-degree color hologram was developed by the Electronics and Telecommunications Research Institute in 2015.
  Universal Flash Storage
  The world's first UFS memory cards were developed by Samsung.
  Rollable keyboard
  The world's first solid rollable keyboard was introduced by LG in 2015.
  Flexible battery
  In 2012, researchers at KAIST demonstrated the first fully functional all-flexible electronic battery system. In 2013, scientists led by Professor Lee Sang-young of Ulsan National Institute of Science and Technology developed the world's first bendable lithium ion batteries.
  High Bandwidth Memory
  High Bandwidth Memory is a high-performance RAM interface for 3D-stacked DRAM developed by SK Hynix and AMD to be used in conjunction with high-performance graphics accelerators and network devices.
  Wearable thermoelectric generator
  Researchers led by Byung Jin Cho at KAIST developed a glass fabric-based thermoelectric (TE) generator that is extremely light and flexible and produces electricity from the heat of the human body.
  Transparent resistive random access memory
  Transparent resistive random access memory (TRRAM) is the world's first transparent computer chip, invented by scientists at KAIST.
  Online electric vehicle
  Researchers at KAIST developed an electric transportation system in which online electric vehicles (OLEV) get power wirelessly through the application of shaped mag
