The article links to this article which describes better how it actually works.

"Reading the memory consists of a simple, one-dimensional scan, because it is self-formatted into precise tracks. There is no need to search in two dimensions for the location of a bit. The signal is highly predictable since all atoms have the same shape and occur on well-defined lattice sites. That allows for a high level of filtering and error correction"

"Writing is more difficult. While atoms can be positioned controllably at liquid helium temperature, that is much harder to achieve that at room temperature"
