An alternative to warehouses. The Memory Unit can store an infinite amount of a single item type. The more items you store, the more power it will require! Continuation fork of notnotmelon's Memory Storage: Factorio 2.1 support and bug fixes only, no new features and no balance changes. Retires if the original updates.
Mods introducing new content into the game.
Version: 1.6.11
Date: 2026-08-10
Features:
- Units built under the original mod are now adopted automatically when you switch to this fork, with their stored contents restored. A mod's saved data is keyed to its internal mod name, so this fork previously saw none of your existing units: they showed a blank window and stopped absorbing and refilling. Nothing was ever destroyed - switching back restored it - but the fork was useless on an existing factory. Each unit's total is read back from the hidden constant combinator it publishes to the circuit network, which is a world entity rather than mod data. You do not have to empty, pack or move anything.
- The stored amount now appears in alt-mode immediately after adoption, instead of staying blank until the first item moved in or out.
Info:
- A circuit signal is a 32-bit integer, so a unit holding more than 2,147,483,647 items is restored to that amount. The mod says so in chat rather than rounding quietly.
Version: 1.6.10
Date: 2026-08-09
Bugfixes:
- Memory unit ghosts no longer carry stored contents, which could duplicate the entire contents of a unit on any ghost-mediated build (blueprint, undo, super-force-build, construction robots, repair turrets).

- Fixed the powersource and combinator being created on the neutral force when a memory unit is cloned and its hidden entities are already invalid.
- Mining or destroying a memory unit that is missing from storage.units no longer crashes the save.
