Countably zero-dimensional space
From Encyclopedia of Mathematics
A normal space 
that can be represented in the form of a union 
of subspaces 
of dimension 
.
Comments
If 
is a metrizable space, then its countable zero-dimensionality is equivalent to it being countable dimensional, i.e. being the union of countably many finite-dimensional subspaces.
