This is a super specific part for vintage computer or electronics repair. It's one brand new HY53C464LS-80 integrated circuit chip from Hyundai. It's a MOS DRAM (Dynamic Random-Access Memory) chip with a capacity of 64K words by 4 bits. It comes in the classic DIP-18 package (that's the black plastic package with 18 pins for through-hole soldering). The manufacturer part number is HY53C464LS80. It's an active component, made in the Republic of Korea (South Korea). The listing mentions stock codes P12 and P19. The EAN is 3456761004196. If you're restoring an old computer, arcade game, or piece of industrial equipment from the 80s or 90s and need this exact memory chip, here it is. It comes new in its packaging, probably an anti-static tube. A must-have for niche tech repairs.
