Is your memory failing and perhaps need a memory boost? I read with interest an article claiming that card-games, Sudoku and crossword puzzles are no longer adequate in boosting one's memory or to slow down memory deterioration. There are many sources where brain training exercises are available. They range from self-help books to computer games.
In the past, memory is what we associate with our brain and neurons but in this time and age, memory most times refer to that of computers and other contemporary playthings. So, a common question could be "How much memory would you need?", which decades ago, would seem irrelevant.
