    Massive data turn to 0x00 unexpected using NOR Flash AM29F032B

    tanggr2015_2957811

      Hello, Techteam

      We've been using the NOR Flash AM29F032B for several years on our products. A strange event has been occurred twice during these years. Data of some address units all turned into 0x00 when the programm only read the flash. The throuble address units are as follow:

      Product No.1

      0x1--0x4FE40

      0x4FE81--0x4FF40

      Product No.2

      0x1--0xF4240

      0xF4301--0xF431E

       

      We are sure that our timing design is correct as the datasheet informed. Could you please explain the reason for this event? Thank you very much!
