In VS Code today, when someone inspects memory, we open the hex editor and never automatically close it. The first question is, should be memory view be automatically closed at any point? This would definitely make sense when the session ends -- it still has the data it's currently displaying, of course, but interacting with it or scrolling around and requesting data outside the loaded bounds would not work.

The next natural question is whether the memory should be closed when the debugger is resumed. At the moment, variable references are assumed tied to the current stackframe and invalid after that point. This is fine, since variables are only displayed when the debugger is paused and the view showing all variables in the editor is renewed on the next pause. However, the memory view displays a single variable, and it could be desirable for the user to keep it open as a "watch" view.

One way to make this work would be to suggest debug adapters reuse memoryReferences between pause events, and suggest that, if an editor is displaying an view corresponding to a previously-seen memoryReference, it should treat any later-seen equal memoryReference and referencing the same memory region. Editors can then have similar behavior to their "variables" view, where the binary contents are shown as available when paused and a reference is present, and unavailable when the program is resumed.
