Row Address Width

Sets the number of row address bits. The Row Address Width determines which Component Density values are available. Larger row address widths support higher-density devices.

LPDDR5 SDRAM
Valid values: 13, 14, 15, 16, 17. Default: 15.
DDR5 SDRAM
Valid values: 16, 17, 18. Default: 16.

Bank Address Width

Sets the number of bank address bits.

LPDDR5 SDRAM
2 (fixed).
DDR5 SDRAM
2 (fixed for all component widths).

Bank Group Width

Sets the number of bank group address bits. The supported values depend on the Controller Type and Base Component Width.

LPDDR5 SDRAM
2 (fixed).
DDR5 SDRAM (x4/x8)
3 (fixed, 8 bank groups).
DDR5 SDRAM (x16)
2 (fixed, 4 bank groups).

Component Density

Selects the capacity of each individual DRAM component. The available density options depend on the memory device type and the selected Row Address Width.

Valid values
2Gb, 3Gb, 4Gb, 6Gb, 8Gb, 12Gb, 16Gb, 24Gb, 32Gb, 64Gb

Memory Density per Channel

Displays the computed total memory capacity per channel or per DIMM.
