Write Protect
Write Protect bus operations are used to protect the memory against program or erase
operations. When the Write Protect signal is Low the device will not accept program or erase
operations and so the contents of the memory array cannot be altered. The Write Protect
signal is not latched by Write Enable to ensure protection even during power-up.
Standby
When Chip Enable is High the memory enters standby mode, the device is deselected,
outputs are disabled and power consumption is reduced.
