WebJul 27, 2024 · NAND flash memories have been widely used in smartphones, personal computers, data centers, etc. Thanks to these two key technologies: (1) continued scaling down process technology and (2) multilevel (e.g., MLC, TLC) cell data coding, the storage density of a NAND flash memory has been significantly increased over previous decades . WebNAND flash devices, available in 128Mb to 2Tb+ densities, are used to store data and code. Low-density NAND flash is ideal for applications like automotive, surveillance, machine-to-machine (M2M), IPC, automation, printers and home networking while high-density NAND flash is most commonly used in data-heavy applications like SSDs, …
