Statement of Volatility – Dell 2408WFP Monitor
The purpose of this document is to certify that the Dell 2408WFP monitor will not save,
retain, or reproduce a signal to any internal or external component after power has been
removed and reapplied to the unit.
The Dell 2408WFP monitor contains both volatile and non-volatile (NV) memory ICs. Volatile
memory(s) lose their data immediately upon removal of power. Non-volatile memory ICs
continue to retain their data even after the power has been removed. However, no input
video data is written into these memory ICs during operation.
List below contains volatile and non-volatile memory ICs used in the Dell 2408WFP monitor.
