MX29GL512

Hi guys I am using the MX29GL512F parallel EEPROM chip for my project. See I need a parallel EEPROM chip to store data and quickly retrieve 16bit data from the EEPROM chip when the system is running. So I dont understand the data sheet completely. I mean take for instance to read the silicon ID of chip the same operation if performed a when you read a memory address 0x0200 of any sector!!! How then does the device differentiate! Ok, now comes reading what they call the status register, for example I need to tell when the program operation has been completed... Ok so I basically perform a read operation but remember the device goes back to READ mode after it finished programming.... How do I know if the system is reading the memory array or the status BIT. 

GUYS please help... anyone who has used this CHIP before, or anyone who knows another chip that can provide 33Mx16 bits... no passwords or funky codes something real simple

    I think this section is intended for Microchip memories, that chip is made by Macronix...

    ... to read the silicon ID of chip the same operation if performed a when you read a memory address 0x0200 of any sector!!! How then does the device differentiate!

    There is one vital difference. You have to apply 10V to the A9 pin to activate" Read ID" mode!
     
    When you are reading the status register, Q6 will toggle.
    That means it changes state every time you read the location.
