When the first IBM 65 was wheeled into Shell Oil Melbourne, I think it had 256K of memory. And I believe it did cost a million or so. Of course, it was made from core memory with real wires. Very expensive to thread those wires, I suspect!!!

AFAIR I read about memory prices in some book about mainframes.
According to the book the ferrite memore cost was 1.3 USD per BYTE at the beginning of S/360 and quickly dropped to 1.0 USD/BYTE.
So, 1MB was over million dollars.
BTW: At the time of CP/M (late 70's/erarly 80's) cost of 64kB RAM was about 100k PLN (polish currency), it's about 30k USD - at current prices.


BTW: Lately IBM claimed that 1GB of memory for mainframe costs 8000USD. It is few *hundreds* times more than market price for memory in PC (which is not much different).
Nowadays mainframe memory prices have dropped down significantly.
