Signal Memory

One bit. Two ways to remember it.

Ready to rememberDiscoveries: 0 / 2
A latch follows data while enable is high. A flip-flop stores data at a rising clock edge and holds it afterward.

A signal with a past

First open and close a data latch. Then compare a clock edge with a clock that simply stays high. Predict, apply a step, and collect the evidence. Hints and retries are free.

D is a prepared data bit; Q is the stored bit. Each investigation starts at Q = 0. A real chip does not necessarily start at 0.

Learning Focus Compare stored states and explain the changes. Practice, not a subject grade.

Fun fact: A two-bit memory can hold four different patterns: 00, 01, 10 and 11.

This is an ideal digital model. No batteries, tools or physical build are needed. Practice does not award grades or coins.
