188.8.131.52. Command and Address Signals
Although DDR4 operates in fundamentally the same way as other SDRAM, there are no dedicated pins for RAS#, CAS#, and WE#, as those are shared with higher-order address pins. DDR4 has CS#, CKE, ODT, and RESET# pins, similar to DDR3. DDR4 also has some additional pins, including the ACT# (activate) pin and BG (bank group) pins.
