Samsung, the world’s top memory chip maker, also produces logic chips designed by customers through its foundry business. Tesla CEO Elon Musk said the U.S. automaker had signed a $16.5 billion deal to source chips from Samsung Electronics, a move expected to bolster the South Korean tech giant’s loss-making contract manufacturing business.Musk said Samsung’s new chip factory in Taylor, Texas will make Tesla’s next-generation AI6 chip, potentially re-energizing the project that has faced long delays amid Samsung’s difficulties in retaining and attracting major clients.Samsung currently makes Tesla’s AI4 chips, which power its Full Self-Driving driver assistant system, while TSMC is slated to make the AI5, initially in Taiwan and then Arizona. Is is the right time to buy SamSung stock?
