Hello All,

I have a doubt of using x16 SDRAMs for DDR4 design.
Is it feasible to design 4Nos of x16 DRAM and 1No of x8 DRAM for ECC ? to make x72 bits ?
In that case, How do we connect BG1 for ECC ? Point to point connection ?

Else we have to use x16 DRAM for ECC and give no connect for the MSB nibbles ?
Please help.

Regards,
Vineeth Sankarakutty

Your device's memory controller should have detailed documentation on how to implement ECC in all possible configurations.
