tCCD_S指的是不同bank group地址延迟时间，tCCD_L指的是相同bank group列地址延迟时间。
(Identifier: DDR5_MEM_DEVICE_TCCD_L_WR2_CYC) tRRD_S Specifies the Activate-to-Activate command delay to different bank group for 1KB page size in cycles. Note: This parameter can be auto-computed. (Identifier: DDR5_MEM_DEVICE_TRRD_S_CYC) ...
Fine Offset for Minimum CAS to CAS Delay Time (tCCD_Lmin), same bank group.This Byte modifies the calculation of SPD Byte 40 with a fine correction using FTB units. The value of tCCD_Lmin comes from the SDRAM data sheet. This value is a two’s complement multiplier for FTB units, ...
(Identifier: MEM_TCCD_L_WR_NS) tCCD_L_WR2 Specifies the write CAS_n to write CAS_n command delay for same bank group and the second write is not RMW, in nanoseconds. (Identifier: MEM_TCCD_L_WR2_NS) tRRD_S Specifies the Activate-to-Activate command delay to di...
tCCD_L_WR Specifies the write CAS_n to write CAS_n command delay for same bank group in nanoseconds. (Identifier: MEM_TCCD_L_WR_NS) tCCD_L_WR2 Specifies the write CAS_n to write CAS_n command delay for same bank group and the second write is not RMW, in nanosecon...
