Examples of MLC memories are MLC NAND flash, MLC PCM (phase-change memory), etc. For example, in SLC NAND flash technology, each cell can exist in one of the two states, storing one bit of information per cell. Most MLC NAND flash memory has four possible states per cell, so it can store two bits of information per cell. This reduces the amount ...
a standard physical interface for NAND flash in TSOP-48, WSOP-48, LGA-52, and BGA-63 packages; a standard mechanism for NAND chips to identify themselves and describe their capabilities (comparable to the Serial Presence Detection feature of SDRAM modules) a standard command set for reading, writing, and erasing NAND flash
Multi-level cell (MLC) flash memory was introduced by NEC, which demonstrated quad-level cells in a 64 Mb flash chip storing 2-bit per cell in 1996. [ 25 ] 3D V-NAND , where flash memory cells are stacked vertically using 3D charge trap flash (CTP) technology, was first announced by Toshiba in 2007, [ 34 ] and first commercially manufactured by ...
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 ...

Samsung announced that it had begun mass production of multi-level cell (MLC) flash memory chips using a 10 nm process in 2013. [120] On 17 October 2016, Samsung Electronics announced mass production of SoC chips at 10 nm. [121] TSMC began commercial production of 10 nm chips in early 2016, before moving onto mass production in early 2017. [122]
Others – 8.7% Note: SK Hynix acquired Intel's NAND business at the end of 2021 [27] Kioxia spun out and got renamed of Toshiba in 2018/2019. [28] Samsung remains the largest NAND flash memory manufacturer as of second quarter 2023. [29]
Silicon Motion's SM321E and SM324 controllers support SLC and MLC NAND flash from Samsung, Hynix, Toshiba and ST Micro as well as flash products from Renesas, Infineon and Micron. The SM321E is available in a 48-pin LQFP package and a 44-pin LGA package. The SM321E supports up to 4 SLC or MLC NAND flash chips with 4 bytes / 528 bytes ECC
