SK hynix broke Mikron's record and presented the world's highest flash memory — 238-layered

SK hynix today has broken the record recently set by Microsoft. A week earlier, Mikron reported the beginning of supplies of the world's most multi-layered memory 3D NAND — 232-layer crystals. Today, SK hynix has been released, reporting the start of deliveries of 238-layered memory samples 4D NAND. New crystals on a smaller area have higher recording density, lower average consumption, and higher productivity.

It is not hard to assume that SK hynix, like its rival, receives chips with more than 230 layers by putting 128 layered crystals on each other. In the process of wiping, parts of the layers are lost or married, which makes it impossible to achieve an ideal in the form of 256 layered NAND chips, but no one prevents it from reaching it. The Mikron was able to guarantee the production of 232 layered chips, while SK hynix achieved a slightly better result in the production of 238 layer chips. Even such a small advantage would have required the stress of all of the company's technological capabilities.

Mass production of the introduced novels will begin in the first half of 2023 and the first company will produce 512-Gbit chips, recording three bits in each cell and moving to the charge box instead of using a floating shut-off cell, which at least reduces leakage currents.

According to the company, the decrease in the size of the crystal resulted in a 34% increase in the production of chips from each silicon plate compared to the 176 layer memory, with a 50% or 2.4 Gbit/s transmission rate compared to the previous generation. The amount of energy used to read the data decreased by 21%, also in line with the company's obligations to follow the Green Agenda.

The first product with a new memory will be the SSD for personal computers and laptops. Then the 238 layered 4D NAND SK hynix will be placed in smartphones and server storage devices.
