VDDS_MEM_1P1 (LPDDR4 SDRAM IO supply (Sources the LPDDR4 SDRAM VDD2 and VDDQ power rails)) is recommended to be powered from the same power source as VDDS_DDR (DDR PHY IO supply).
VDDS_MEM_1P1 and VDDS_DDR power rails are connected to 1.1 V (LPDDR4).
VDDS_MEM_1P8 (LPDDR4 SDRAM Core supply (Sources the LPDDR4 SDRAM VDD1 power rail)) is 1.8 V.
For more information, refer the Recommended Operating Conditions section in the Specifications chapter of the device-specific data sheet (AM625SIP – AM6254 Sitara™ Processor with Integrated LPDDR4 SDRAM).
