DRAM energy in cacti_wrapper.py

[suyashbakshi]

The cacti_wrapper.py has references for DRAM energies of LPDDR and GDDR5. For LPDDR4, it is listed as "public data" and no references for rest of the memory types. Is it possible to get the references from where the energy formulas for LPDDR4, DDR3 and HBM2 were derived from?

Thank you

Those numbers were taken from some papers, but unfortunately, we don't have a record in hand, sorry. If you would like to have a more concrete reference, you can use cacti (e.g., https://github.com/HewlettPackard/cacti/blob/master/dram.cfg) to generate DRAM costs and cite the cacti paper.
