A histogram of a normal distribution (say, mean lifetime of a particle) is a 1D histogram. You would have counts of decays vs time. In your example, that would be 2D, but it's not.
A 2D histogram would be more like a heat map. The X axis would be time, y axis version, and the (x, y) value would be memory.
