Memory Circuits

MEMORY CELL (ADDRESSABLE)

A circuit that stores a value and can be written to or read from using address/control signals. Multiple cells form a register or RAM. Foundation for redstone computers.

When to Use

Redstone computers, programmable combination locks, stored password systems, ROM data storage.

Materials

  • Multiple Redstone Torches
  • Repeaters
  • Comparators
  • Levers
  • Solid Blocks

How to Build

  1. 1Build a row of RS latches or locked repeaters (one per bit).
  2. 2Add a Write Enable line that gates all data inputs simultaneously.
  3. 3Add a Read Enable line that passes the stored values to the output bus.
  4. 4For addressing: use a decoder to select which cell to read/write.
  5. 5For ROM: use torch patterns on blocks where torch=1, no torch=0.

Variants

  • RS latch array (one RS latch per bit, simple but large)
  • Locked repeater memory (compact, uses repeater lock feature)
  • Comparator memory (analog, stores signal strengths 0-15)
  • ROM (read-only, torch pattern encodes fixed data)
