Solution
Here is a list of the current information on some of our static DIO devices. The list below contains the types of memory in each device, the amount, and whether or not the information stored in that memory is retained. Volatile memory loses its contents when the device is powered off while nonvolatile memory retains its contents when the device is powered off.
USB-6525 :
| Storage Type | Size | Volatility | Access Restrictions |
| Flash Memory | 16 kB | nonvolatile for configuration | Software protected. No mechanism provided for writing to the EEPROM through the user API. No user data is stored in the EEPROM. |

| EEPROM | 64 kb | nonvolatile for configuration | Software protected. No mechanism provided for writing to the EEPROM through the user API. No user data is stored in the EEPROM. |
| EEPROM | 256 kb | nonvolatile | Hardware protected |
PCI/PXI-6528 :
| Storage Type | Size | Volatility | Access Restrictions |
| Flash memory | 1 Mb | Nonvolatile | Not write protected. The user may store power-up states for output channels inside this memory device. User settings may be cleared through the API. The remaining space inside this memory device is used for configuration information and is not user accessible. |
