CopyOnWriteDump is a tool that uses the Process Snapshotting APIs available in Windows 8.1+ and Windows Server 2012 R2+ to capture full memory dumps of Win32 user-mode processes.

Process Snapshotting APIs use Copy-on-Write semantics to capture a "snapshot" of the target process. The target process is suspended for the duration of snapshot creation (its latency is usually orders of magnitude lower than capturing a full memory dump) and is then resumed.
