Icheon is home to Hynix, the world's second largest memory chip maker. The data in a semiconductor memory chip is stored in tiny circuits called memory cells. Every LTO cartridge has a cartridge memory chip inside it. Earlier JP1 circuit board designs employ an EEPROM memory chip. It is the basis of every microprocessor, memory chip and telecommunication circuit in commercial use. The control board has its own memory chip. STMicroelectronics also demonstrated quad-level cells in 2000, with a 64Mb NOR flash memory chip. It can take up to 10 weeks to produce a flash memory chip. It was commercially introduced as a 16Mb memory chip by Samsung Electronics in 1998. His memory chip is re-obtained and he is cloned. In February 2005, Samsung introduced the first prototype DDR3 memory chip. The first HBM memory chip was manufactured by SK Hynix in 2013. It was a modified MOS dynamic RAM (DRAM) memory chip. The first HBM memory chip was produced by SK Hynix in 2013. "Dawn" carries a memory chip bearing the names of more than 360,000 space enthusiasts.
