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.
Flash memory packages can use die stacking with through-silicon vias and several dozen layers of 3D TLC NAND cells (per die) simultaneously to achieve capacities of up to 1 tebibyte per package using 16 stacked dies and an integrated flash controller as a separate die inside the package.
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 .

Charge trap flash (CTF) is a semiconductor memory technology used in creating non-volatile NOR and NAND flash memory. It is a type of floating-gate MOSFET memory technology , but differs from the conventional floating-gate technology in that it uses a silicon nitride film to store electrons rather than the doped polycrystalline silicon typical ...
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 ...
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]
The acquisition closed on July 1, 2020. [17] On July 18, 2019, Toshiba Memory Holdings Corporation announced it would change its name to Kioxia on October 1, 2019, including all Toshiba memory companies.
1 : 1.3 Most SSDs use non-volatile NAND flash memory for data storage, primarily due to its cost-effectiveness and ability to retain data without a constant power supply. NAND flash-based SSDs store data in semiconductor cells, with the specific architecture influencing performance, endurance, and cost.
