SK Hynix Shows Off 321-Layer 3D TLC NAND Device
 

SK Hynix showcased its 321-layer TLC NAND memory at the Flash Memory Summit 2023. The South Korean company is the first NAND maker to publicly demonstrate 3D NAND with over 300 layers. Although such memory is expected in mass production in 2025, the demonstration is meant to showcase SK Hynix's preparedness for the next wave of non-volatile memory technology.
