In 2013, Samsung introduced V-NAND (Vertical NAND, also known as 3D NAND) with triple-level cells, which had a memory capacity of 128 Gbit. [27] They expanded their TLC V-NAND technology to 256 Gbit memory in 2015, [24] and 512 Gbit in 2017. [28] Enterprise TLC (eTLC) is a more expensive variant of TLC that is optimized for commercial use.
Toshiba in 2007 [24] and Samsung in 2009 [25] announced the development of 3D V-NAND, a means of building a standard NAND flash bit string vertically rather than horizontally to increase the number of bits in a given area of silicon. Figure 6. Vertical NAND structure. A rough idea of the cross section of this is shown in figure 6.

In July 2016, Samsung announced the 4 TB [clarification needed] Samsung 850 EVO which utilizes their 256 Gbit 48-layer TLC 3D V-NAND. [183] In August 2016, Samsung announced a 32 TB 2.5-inch SAS SSD based on their 512 Gbit 64-layer TLC 3D V-NAND. Further, Samsung expects to unveil SSDs with up to 100 TB of storage by 2020. [184]
Solar eclipse glasses can keep your eyes safe during an eclipse, but they need to meet special certifications. Here are the best ones and where to free pairs. Are Solar Eclipse Glasses a Scam?
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
If you've been on social media (especially TikTok) even a little recently, you've probably seen an ad for Pair Eyewear. While other glasses-by-mail companies compete largely on price, Pair is all ...
