Tiny RAM simulator

Read, write, and inspect all sixteen addressable bytes.

Prediction before clicking

A four-bit address selects one of sixteen independent bytes, each of which can be replaced by a write.

What the simulator is showing you

A four-bit address selects one of sixteen independent bytes, each of which can be replaced by a write.

Try to predict the next output before changing the input. A prediction is evidence that you understand the mechanism. If the result surprises you, trace the bit values or the stored state explicitly.

These experiments are simplified teaching models. The rules are intentional and inspectable, but they do not simulate transistor propagation delay, power consumption, or real processor pipeline details.
