Sk hynix begins mass production of its 72 layer 3d nand
Table of contents:
Last April SK Hynix announced its fourth generation of 72-layer 3D NAND memory, which achieves a storage density per chip of 256 Gb and offers a level of productivity similar to Samsung's 64-layer memory.
SK Hynix wins the battle at 72-layer 3D NAND
For the next three months the SK Hynix engineering team has been working very hard to improve the success rate in manufacturing its new 72-layer memory, initially the performance was less than 50% so there was quite a concern.

Finally SK Hynix has managed to win the battle after very hard work by all its team, with which the manufacturing performance of its 72-layer 3D NAND memory has risen dramatically and is already reaching the levels achieved by Samsung with its chips 64-layer. Samsung is the undisputed leader in memory manufacturing so having caught up with the South Korean giant is quite an achievement.
SK Hynix has also started working on its own controller to avoid dependence on third-party controllers, thereby having all the elements to fully produce the SSDs, which will mean a greater profit margin and greater competitiveness.
