So, after all, what is time dilation? You see the picture, if a particle is unmoving, stationary, it will move forward at the maximum rate possible, but the more the particle moves through the space, the less it has influence in the time dimension, then dilating the time dimension.

You can simulate the 4004 like the 6502 (see https://t.me/c/1123530133/73), but it seems you need to run on an older Java version.

Take a look at the simulation running:

If you want to understand the basic process of IC reversing, you must read this document. It explains some approaches and forms of IC reversing, from product teardowns (simple disassembly process and analysis) and system analysis (probing technique for functional analysis, for example) to an entire analysis of a microchip, using several processes to extract the circuits and make the schematics.

In the case study you can see the explanation of how they got the keys to break the encryption. Despite EEPROMs have protection mechanisms to avoid this, you can break it, i will send here soon.

This post is focused on security in microcontrollers and the common techniques used to read protected data.

In this example, he applied UV light in the protection fuses to enable reading of the program memory. This can be mitigated by using a logic sequence that erases the data present in the data and program memory after changing the state of the fuse:
