After reading the core memory stuff I realized the what I was thinking
about was dynamic memory (16k chips) for a 2 mhz 8080 in byte. The
reason
I got confused was it used the split memory cycle read-write as core
memory.
Core is one of the few destructive readout memories used. So every
read has a following write to restore the data, often between data
read there will be a modify cycle which means new data written back.
