Arcade games have utilized various storage solutions throughout their history to preserve crucial data like high scores, game settings, and progress. The most common method in classic arcade cabinets was Battery-Backed RAM. A small battery, often a lithium coin cell, provided continuous power to a dedicated RAM chip, preventing data loss when the machine was turned off. While effective, these batteries eventually died, leading to the infamous "high score reset".

As technology advanced, EEPROM (Electrically Erasable Programmable Read-Only Memory) chips became the standard. These non-volatile memory chips could be written to and erased electrically without needing a constant power source, making them far more reliable than battery-backed solutions.

For modern arcade systems and retro reproductions, Flash Storage and SD Cards are increasingly common. They offer greater storage capacity and ease of access for operators to update software or back up data.

Finally, some contemporary arcades connected to networks may use Cloud Storage, synchronizing player profiles and scores across multiple machines in a wider network. This represents the latest evolution in ensuring that a player's achievements are permanently saved.
