SK Hynix teases its 8th Gen 3D NAND flash with 300 layers
SK Hynix 300-layer NAND flash teased
The corporate is nearing the contest of its eighth Gen 3-D NAND era, stocks Tom’s {Hardware}(*18*). (*10*)
(*1*)
SK Hynix has been at the leading edge of inventions with their multi-layer NAND era. Best in August final yr, the corporate introduced the advance of 238-layer 4D NAND flash reminiscence. This reminiscence is predicted to go into mass manufacturing within the first part of this yr. However as this era enters the marketplace, SK Hynix is now taking a look additional.
Tom’s {Hardware} has new knowledge at the long term eighth Gen 3-D NAND era. It could function greater than 300 layers enabling 1Tb (128GB) capacities at a far upper density of 20 Gb in step with sq. mm. It could have the speedier throughput than 238-layer reminiscence through 18%, achieving as top as 194 MB/s.

The corporate shared their objectives in attaining upper density NAND flash, together with:
- (*20*)Triple-Test Program (TPGM) function that narrows mobile threshold voltage distribution and decreases tPROG (program time) through 10%, which interprets into upper efficiency;
(*20*)Adaptive Unselected String Pre-Fee (AUSP) — any other process to scale back tPROG through round 2%;
(*20*)All-Cross Emerging (APR) scheme that reduces tR (learn time) through roughly 2% and cuts phrase line emerging time;
(*20*)Programmed Dummy String (PDS) method that cuts global line settling time for tPROG and tR through decreasing channel capacitance load;
(*20*)Airplane-Stage Learn Retry (PLRR) capacity that permits to switch learn degree of a airplane with out terminating others due to this fact issuing next learn instructions right away and bettering high quality of carrier (QoS) and due to this fact learn efficiency.
Sadly, there are not any reputable main points in this 300-layer reminiscence but. The slide and knowledge is most probably from the new ISSCC presentation. Actually, there’s no point out of this upcoming tech at the SK Hynix web page but, so it’s unclear when would this era input mass manufacturing. Then again, 2024 can be a excellent bet.
