Nand flash page read

WitrynaIn my experience, all of the older flash chips allow you to change any 1 bit to a 0 bit without an erase cycle, even if that bit is in a page or even a byte that has already had other bits programmed to zero -- a page of flash can be programmed multiple times between erases. (This is called "multiple-write" in the YAFFS article). Witryna21 kwi 2008 · NAND Flash Applications Design Guide from Toshiba (explains the low-level details of interfacing with common NAND flash chips) 3.1 Page Read.
