SK hynix has developed new 4D NAND flash with an enormous 238 layers, paving the way in which for speedy and capacious new SSDs, the corporate has introduced.
Unveiled on stage at Flash Reminiscence Summit in Santa Clara, the brand new reminiscence chip is described because the “world’s first 238-layer 512Gb TLC 4D NAND” and is anticipated to enter mass manufacturing within the first half of 2023.
In contrast with the earlier 176-layer mannequin, the brand new NAND is alleged to supply 50% quicker information switch speeds (at 2.4Gb/sec), 21% higher vitality effectivity for information reads and a 34% enhance in total productiveness.
The arrival of the 238-layer product will see SK hynix snatch the document for world’s highest NAND stack from rival producer Micron, whose newest mannequin contains a measly 232 layers.
238-layer 4D NAND flash
NAND flash is a sort of non-volatile reminiscence that options in all types of storage units, from reminiscence playing cards, USB sticks and moveable drives to SSDs for servers and consumer units.
The final development in NAND flash improvement is in direction of a discount in value per capability and a rise storage density, successfully eliminating the final remaining use circumstances for conventional laborious disk drives. The arrival of the 238-layer product from SK hynix marks one other step on this journey.
In contrast to different NAND merchandise available on the market, the newest chips within the firm’s vary characteristic a “4D” structure, whereby the logic circuits are positioned beneath the storage cells. SK hynix says this design permits for a “smaller cell space per unit, resulting in increased manufacturing effectivity”.
“SK hynix secured world top-tier competitiveness in perspective of value, efficiency and high quality by introducing the 238-layer product primarily based on its 4D NAND applied sciences,” stated Jungdal Choi, Head of NAND Improvement at SK hynix.
Maybe opposite to expectation, the brand new 238-layer NAND will first make its solution to consumer units, which is able to give content material creators and PC avid gamers trigger for pleasure. Solely later will the brand new chip come to smartphones and high-capacity servers.
SK hynix additionally revealed it’s growing a 1Tb 238-layer product, which is able to double the storage density of the newest chip when it arrives subsequent 12 months. “We’ll proceed improvements to seek out breakthroughs in technological challenges,” added Choi.
