However, despite it being an improvement to its old pal, today's EEPROM's way of holding information is the exact same of the flash memory. • The NOR flash has very slow erase speed compared to NAND flash, and the write speed of the NOR is also slow. However, command list is partially the same so we don't know if it is compatible. 0000167603 00000 n 0000004088 00000 n 0000004863 00000 n NAND flash was invented by Toshiba.
