  "title": "How Alan Turing Designed Early Computer Memory Systems",
  "original_title": "Data storage transfer means for a digital computer",
  "summary": "A 1951 patent by Alan Turing and colleagues describing methods for moving data between different storage types in early digital computers.",
  "what_it_does": "This patent describes a system for managing data movement between a high-speed, limited-capacity memory (like a delay line or register) and a larger, slower secondary storage medium. It focuses on the timing and synchronization required to transfer information chunks between these two tiers. By using specific control signals, the system ensures that data is correctly addressed and read or written without losing the sequence of bits. This was essential for computers that used acoustic delay lines, where data had to be constantly refreshed.",
  "what_it_does_not_cover": [
    "Does not cover modern solid-state drive (SSD) flash memory architectures.",
    "Does not cover graphical user interface (GUI) data management.",
    "Does not cover cloud-based distributed storage systems.",
    "Does not cover non-digital or purely mechanical calculating machines."
