4 Line Direct Mapped Cache Metadata Schematic (1.21.x) – Redstone Computer Memory Cache Build

4 Line Direct Mapped Cache Metadata Schematic brings a working piece of computer memory into your Minecraft world using redstone. This build acts as a small brain to store and check data signals. It uses logic gates to read an 8-bit address space, making it a neat addition for players who build large redstone computers.

Features:

• Redstone Memory: Acts as a direct-mapped cache to hold metadata using vanilla blocks.
• Checks valid and dirty bits to see if the stored information is fresh or needs updating.
• Uses a 2-bit line index and a 3-bit tag to organize the incoming redstone signals.
• Works best with a 3-bit offset, giving it a total 8-bit address space for data storage.
• Fits into a compact 18 by 18 by 21 block area.
• Contains exactly 1,798 blocks, mostly consisting of redstone components and building blocks.
• Runs completely in vanilla Minecraft without needing extra mods.
