Nand threshold voltage
Witryna27 paź 2024 · It means that the stored values in other cells cannot affect the state of the NAND string. Now that the other cells are made temporarily irrelevant, we are able to specifically read the value of our target cell. Generally, we read a cell's state by applying a certain voltage (0 to 4 volts) to the cell's control gate.
