If there's something we know about real life it is that people die, and sometimes these people happen to be related in some way to a creator or a work. It's not uncommon to see works being dedicated to a dead person in the form of an In Memoriam, but sometimes creators might go an extra mile.
A Memorial Character has the purpose of honoring a dead person, be they someone close to the creator or just a simple fan, by immortalizing them in the work. In its most basic form, this is done by giving an already existing character the name of the person they are honoring (or at least part of it), making these characters a subtle way to commemorate them.
Other times, a whole new character might be created in their honor. Also sharing their name, these are usually minor characters that show up at some point in the story, acting as another part of the world without any particularly obvious hint to the true meaning behind their presence to those viewers not in the know.
Particularly strong cases might have a whole new important character being created in the person's memory, or a whole new work being made with them as the centerpiece, but these are obviously restricted to the creator's family or the closest of friends.

- The Elder Scrolls V: Skyrim has a retroactive case of this: Erik the Slayer is an inhabitant of Rorikstead who was based on Erik West (internet alias Immok the Slayer), a visitor to Bethesda's headquarters that surprised the creators for his knowledge of Oblivion. He passed away from cancer in May of 2011, before he had the chance to see his character in-game, making his presence in the game all the more meaningful.
