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]

The MicroLatency flash modules were updated to 32-layer 3D TLC NAND flash from Micron. Rather than the compression feature slowing down data access as usually happens with software based compression, the 900 continued to advertise 1.2 million I/O operations per second (IOPs) due to the hardware compression implementation and hardware only data ...
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]
