The Nintendo 64 Controller Pak (model NUS-004) — often called an N64 memory card — was the console’s equivalent of a PlayStation memory card, allowing players to save game progress directly from compatible titles.
Most original N64 memory paks had a 256KB capacity divided into 123 pages of save data. These early versions relied on an internal CR2032 battery to preserve saved files, meaning data could be lost once the battery expired — typically after 10–20 years of use.
Over time, modern upgrades introduced FRAM (Ferroelectric RAM) memory, which doesn’t require a battery, allowing game saves to last indefinitely. These battery-free options are often referred to as Forever Paks, such as the Forever Pak by 4 Layer Tech, designed to provide permanent saves without any maintenance.
In this collection, you’ll find:
- Original-style N64 memory paks and replacement batteries
- Forever Pak battery-free FRAM memory cards for long-term data retention
- Gamebit security tools, solder, and desoldering braid — everything needed to open, repair, or upgrade your N64 memory card
Whether you’re restoring an original Controller Pak, replacing a worn-out memory card, or wanting to upgrade to a Forever Pak for battery-free saves, we’ve got you covered.
