REV. 1.6, OCT. 24, 2014

COMMAND DESCRIPTION

(1) Write Enable (WREN)

The Write Enable (WREN) instruction is for setting Write Enable Latch (WEL) bit. For those instructions like PP, SE,

BE, CE, and WRSR, which are intended to change the device content, should be set every time after the WREN in-

struction setting the WEL bit.

The sequence is shown as

.

(2) Write Disable (WRDI)

The Write Disable (WRDI) instruction is for resetting Write Enable Latch (WEL) bit.

The sequence is shown as

The WEL bit is reset by following situations:

- Power-up

- Write Disable (WRDI) instruction completion

- Write Status Register (WRSR) instruction completion

- Page Program (PP) instruction completion

- Sector Erase (SE) instruction completion

- Block Erase (BE) instruction completion

- Chip Erase (CE) instruction completion
