Energetic Cost of Erasure

Information structures resist deletion due to energetic cost

A4: Energetic Cost of Erasure

Formal Definition (Landauer’s Principle)

Eerase ≥ kB · T · ln(2) · H(x)

Erasing information requires energy. Even a single bit costs at least kBT ln(2) joules. Structured, low-entropy patterns have a thermodynamic cost to destroy.

In the ASH Model

The error-correcting codes provide an analogous mechanism: random noise cannot easily destroy structured patterns because the code actively restores corrupted states within the Hamming bound.
