DDR5 Power Management

DDR5 module Both server and client will have PMIC on the DIMM Module

Benefit for DRAM

  • PMIC can separate the power noise between mother board and DIMM
  • PMIC provides more stable power to DRAM

Benefit for systems

  • It reduces the number of  VR on mother board
  • Simpler socket pinout for the DIMM power provision
  • Higher power efficiency (8x% -> 92%), resulting more power margin tolerance
