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.
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]
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.

UFS uses NAND flash. It may use multiple stacked 3D TLC NAND flash dies (integrated circuits) with an integrated controller. [4] The proposed flash memory specification is supported by consumer electronics companies such as Nokia, Sony Ericsson, Texas Instruments, STMicroelectronics, Samsung, Micron, and SK Hynix. [5]

YMTC's 3D NAND flash memory chips were the first to be domestically mass-produced in China. [11] Later in 2018, YMTC announced mass production of its 32-layer 3D NAND flash memory chip, and in September 2019, YMTC reported that it had started mass-producing its 64-layer TLC 3D NAND flash memory chip, with both chips using its Xtacking architecture.
Since 2013, triple-level cell (TLC) (e.g., 3D NAND) flash has been available, with cycle counts dropping to 1,000 program-erase (P/E) cycles. A lower write amplification is more desirable, as it corresponds to a reduced number of P/E cycles on the flash memory and thereby to an increased SSD life. [1]
