The characteristics of NOR Flash are lower
density, high read speed, slow write speed,
slow erase speed, and a random
NOR flash memory wiring and structure on silicon
NAND flash memory wiring and structure on silicon
The characteristics of NAND Flash are:
high density, medium read speed, high write speed, high
erase speed, and an indirect or I/O like access.
density, and high programming and erase speeds make it the best choice.
A NOR flash cell can be programmed, or set to a binary "0" value, by the following procedure:
A NOR flash cell can be erased, or set back to a binary “1" value, by the following procedure:
often referred to as
By this Method the size of the oxide layer can be decreased to very small scale for each flash memory cell.
This way density(cells for unit area) of the flash memory is increased.
