The Controller Pak was the Nintendo 64's solution to the memory card seen in the PlayStation and other CD-ROM-based video game consoles. The standard Controller Pak contains 256 KB memory, which is divided into 123 pages. Bigger memory cards usually made by third parties ranged from around 1-4MB in size. The Controller Pak was mostly used by third parties to store player data. First party games typically used on-cartridge storage (SRAM, EEPROM, or FlashRAM) to store the save data.
