SK Hynix managed to increase the yield rate of 72-layer flash memory 3D NAND to the required level
According to the source, the company SK Hynix were able to increase the percentage of usable products in the production of 72-layer flash memory 3D NAND to the required level and launched its mass production. We will remind, SK Hynix introduced the first 72-layer flash memory 3D NAND in April of this year. Allegedly, at that time, the percentage of yield was below 50%.
SK Hynix uses the new 3D NAND TLC memory in the finished product: solid-state drives and eMMC modules. They are also used by the controllers and firmware of its own design SK Hynix. Delivery of these products to the customers has already begun.
The source notes that the presence of controllers and algorithms developed by the manufacturer of the memory, it is very important, because the resources of the cells below TLC than MLC, so the optimal low-level memory handling is particularly necessary.
