The refresh rate is determined by the parameter tREFI in "mem/DRAMInterface.py". However, if you want a refresh rate of 64 ms you cannot simply set tREFI to 64 ms. tREFI is the time between two refresh commands, while 64 ms usually is the time between two refresh commands to the same DRAM cell. Depending on the selected device size and temperature range you have to set different values for tREFI and tRFC. You can find more information in the JEDEC standard for DDR4.
The self-refresh frequency is not determined by the DRAM controller, but by the DRAM device itself. This parameter cannot be modified via configuration. The only parameter you can modify is tXS (self-refresh exit time). For more information you should also take a look at the JEDEC standard. _______________________________________________ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an email to gem5-users-le...@gem5.org %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s
