Witryna4 gru 2024 · Since the memory cells are connected as strings in NAND Flash, all other cells in the string need to be turned on prior to reading the required cell. A readout voltage (V READ ), higher than the maximum threshold voltage of the memory cells, is applied to the gate terminal of all other cells in the string to turn them on or unselect … Witryna21 lut 2024 · 1. There's a third option: the CPU sends the data to the chip over a bus of whatever width. The chip collects the data in a small RAM buffer, and when it has all the data for a page, it overwrites the entire page with the data from the buffer. Even if the page has to be written all at once, that does not mean the CPU has to send the data … WitrynaIf the status is set to 1 by the Flash, it indicates the Flash finishes the page program operation. Then the nfc_done pulse is sent. This completes the page program operation.
