I'm not a domain expert in epigenetics, but in grad school for bioinformatics I did a bunch of research on nucleosome positioning[0] which is epigenetics-adjacent. "Epigenetic memory" is the term of art I was taught in grad school. Either they've changed that in the last 10 years, or ch4s3 is attempting to assert a different definition of "memory" than the one used in the field. They are also incorrect. DNA methylation is an actual methyl group chemically binding to an actual DNA nucleotide, and staying there. When we flip a bit on a hard drive platter we call that "memory" as well.
