I alread knew this article which only says "Erase operations in NAND Flash are straightforward while in NOR Flash, each byte needs to be written with ‘0’ before it can be erased. This makes the erase operation for NOR Flash much slower than for NAND Flash." without any details on why the cells need to be …

WebThe AT25EU Ultra-Low-Energy SPI NOR Flash with Fast Erase supports power-conscious, size-constrained connected devices. These devices offer a variety of power-saving features including wide V CC (1.65V to 3.6V) operation to extend the battery life as well as the 100nA to 300nA deep power-down mode to conserve energy when the product is not in use.
Web22 de jul. de 2010 · You don't have to erase a flash memory cell before writing to it. However, you can only write to one entire block of cells at a time. Typically these blocks of cells are at least 128KB in size. So suppose you are writing a 4KB file to your SSD. Well, you have to write one 128KB block at a time.
