History and specifics
In the 2360s decade, this location was noted on a star chart showing deployment of Federation and Cardassian Union ships displayed in Captain Benjamin Maxwell's ready room aboard the starship USS Phoenix. (TNG episode: "The Wounded")
On a 24th century viewscreen display of a tactical situation monitor in an alternate timeline where the Klingon Empire was at war with the United Federation of Planets in the year 2366, Memory Gamma was listed on a star chart showing Klingon allied forces in relation to Federation positions. (TNG episode: "Yesterday's Enterprise", TNG reference: The Continuing Mission)
In canon, Memory Gamma was only listed on the "Yesterday's Enterprise" alternate timeline tactical situation monitor showing progress of the Klingon war with the Federation, and a later re-use of this chart in "The Wounded".
