Statement of Volatility – Dell UltraSharp U3818DW Monitor
The purpose of this document is to certify that the Dell UltraSharp U3818DW 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 UltraSharp U3818DW 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.
The list below contains volatile and non-volatile memory ICs used in the
Dell UltraSharp U3818DW monitor.
