Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating gate MOSFETs. They differ at the circuit level depending on ...
Multi-level cell. In electronics, a multi-level cell (MLC) is a memory cell capable of storing more than a single bit of information, compared to a single-level cell (SLC), which can store only one bit per memory cell. A memory cell typically consists of a single floating-gate MOSFET (metal–oxide–semiconductor field-effect transistor), thus ...
Yangtze Memory Technologies Corp (YMTC) is a Chinese semiconductor integrated device manufacturer specializing in flash memory (NAND) chips. Founded in Wuhan, China, in 2016, with government investment and a goal of reducing the country's dependence on foreign chip manufacturers, the company was formerly a subsidiary of partially state-owned ...
Largest NAND flash memory manufacturers. The following were the largest NAND flash memory manufacturers, as of the second quarter of 2023. [ 26 ] Samsung Electronics – 31.4%. Kioxia – 20.6%. Western Digital Corporation – 12.6%. SK Hynix – 18.5%.
Based on its original design, NOR flash memory is designed to store binary code of programs because it supports XIP (eXecute-In-Place) and high performance in read operations, while NAND flash memory is used as a data storage because of its lower price and higher performance in write/erase operations, compared to NOR flash. In recent years, the ...
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 ...
Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. In contrast, volatile memory needs constant power in order to retain data. Non-volatile memory typically refers to storage in semiconductor memory chips, which store data in floating-gate memory cells ...
Website. www.onfi.org. The Open NAND Flash Interface Working Group (ONFI or ONFi[ 1 ] with a lower case "i") is a consortium of technology companies working to develop open standards for NAND flash memory and devices that communicate with them. The formation of ONFI was announced at the Intel Developer Forum in March 2006.
