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.
Table 5.
1. Only for x16 devices.
2. WP must be V
Table 6.
1. Any additional address input cycles will be ignored.
2. The fifth cycle is valid for 2Gb devices. A28 is for 2Gb devices only.
