Reading Array Data

The device is automatically set to reading array data after power up. No commands are required to

retrieve data. The device is also ready to read array data after completing an Embedded Program or

Embedded Erase algorithm.

Following an Erase Suspend command, Erase Suspend mode is entered. The system can read array data

using the standard read timings, with the only difference in that if it reads at an address within erase
