Nand flash testing
Witryna10 gru 2012 · NAND-type memory has a much higher storage density and is by far the most dominant of the two types. In addition to the floating gate, NAND flash memory cells usually have a control gate, drain, source, and bulk (see figure 1). Both during endurance testing and in actual use, a memory cell is repeatedly set (programmed) … Witryna7/26 Disturb Testing Flash Memories Sheldon NAND Flash Errors Modes All NAND flash devices have finite lifetimes and will eventually wear out with repeated use. Each block is an independent unit of storage, and can be erased and reprogrammed without affecting the lifetime of the other blocks. Good blocks can be erased and programmed …
