Some embodiments include methods of forming memory cells. A semiconductor construction may be provided, with such construction including tunnel dielectric material over a semiconductor substrate. The construction may be placed within a chamber. While the construction is within the chamber, a plurality of charge-trapping centers may be dispersed over the tunnel dielectric material. The charge-trapping centers may be nanoclusters formed by sputter-depositing metallic nanoparticles into an aggregation chamber, and then aggregating groups of the nanoparticles into the nanoclusters. Also while the construction is within the chamber, electrically insulative material may be formed over and between the charge-trapping centers. Control gate material may then be formed over the electrically insulative material.
