Arcade machines rely on various types of memory storage to deliver fast and seamless gaming experiences. The most common types include:

1. ROM (Read-Only Memory): Used to store game code and graphics permanently. ROM is non-volatile, meaning data remains even when power is off. Classic arcade games like Pac-Man and Space Invaders used ROM chips.

2. RAM (Random Access Memory): Temporary storage for active game data, such as player scores and level progress. RAM is volatile and clears when the machine is powered down.

3. Flash Memory: Modern arcade machines often use flash memory for updates and additional game content. It’s rewritable and more flexible than traditional ROM.

4. EEPROM (Electrically Erasable Programmable ROM): Stores settings and high scores, allowing data retention without constant power.

These memory types work together to ensure smooth gameplay, quick loading times, and reliable performance in arcade machines.
