Is it true that magnetic core memory stores each bit of data by magnetizing a small ferrite ring in one of two directions?

Yes. A reference article on magnetic-core memory states that core memory uses toroids (rings) of semi-hard ferrite, that each core stores one bit of information, and that applying current magnetizes the core. Other items describe magnetization-direction bit storage in vortex cores or analog flux storage in toroidal cores, which are related but not the same ferrite-ring bit mechanism.
