New NAND flash paves the way for super cheap, extra large SSDs

SK hynix unveils 238-layer 4D NAND flash

According to the business, SK Hynix has created new 4D NAND flash SSDS with a massive 238 layers. Opening the door for quick and large-capacity SSDs.

The new memory chip, dubbed the “world’s first 238-layer 512Gb TLC 4D NAND,” was unveiled live on stage at the Santa Clara Flash Memory Summit. It is anticipated to go into full production in the first half of 2023.

The new NAND flash SSDs is reported to provide 50% quicker data transfer speeds (at 2.4Gb/sec). 21% improved energy efficiency for data reads. 34% boost in overall productivity when compared to the existing 176-layer model.

With the introduction of the 238-layer device. SK Hynix will surpass competitor manufacturer Micron. Whose most recent model only has 232 layers, for the title of having the biggest NAND stack in the world.

238-layer 4D NAND flash

NAND flash is a form of non-volatile memory that is used in a wide range of storage devices. Including SSDs for servers and client devices as well as memory cards, USB sticks, and portable drives.

The final remaining applications for conventional hard disk drives are being largely eliminated by the overall trend. NAND flash development towards a decrease in cost per capacity and an increase in storage density. The 238-layer product from SK Hynix has now arrived, which is another development in this process.

The newest chips in the company’s lineup, in contrast to other NAND products on the market. Have a “4D” layout where the logic circuits are positioned below the storage cells. This design enables a “reduced cell area per unit, resulting in improved production efficiency,” according to SK Hynix.

According to Jungdal Choi, Head of NAND Development at SK Hynix, “by introducing the 238-layer product based on its 4D NAND technology. SK Hynix ensured global top-tier competitiveness in perspective of cost, performance, and quality.”

The new 238-layer NAND will likely arrive on client devices first, perhaps against expectations. Which will be exciting for PC gamers and content producers. High-capacity servers and cellphones won’t get the new processor for some time.

Additionally, SK Hynix disclosed that it is working on a 1Tb 238-layer product that. When released next year, will double the storage density of the most recent chip. Choi continued, “We will keep innovating to find solutions to technology problems.

These are currently the largest SSDs and HDDs available.

Through files and blocks

What is NAND flash used for?

NAND flash has found a niche in devices that are routinely uploaded and replaced with enormous files. The NAND technology is used in USB flash drives, digital cameras, and MP3 players. NAND flash uses electrical circuits to store data and saves information as blocks.

Is NAND flash better?

Greater storage capacities can be achieved without significantly increasing cost thanks to the improved memory density. Better endurance and less power consumption are other benefits of 3D NAND. NAND is a very significant memory technology overall. Because it offers quick erase and write speeds at a reduced cost per bit.

Is NAND faster than SSD?

NAND: Is it faster and easier than SSD?
It may be between 2 and 7 times quicker than SATA SSDs. NVMe can support up to 64,000 queues, each of which can process 64,000 commands continuously.
