Do we need LPDDR4-SDRAM with ECC when using in-line ECC?

For example, ISSI has LPDDR4-SDRAM with and without ECC.

When using in-line ECC with DRA821, is it okay to use LPDDR4-SDRAM without ECC?

Hi,

I am not familiar with LPDDR4 with on-die ECC.

I will confirm, but my understanding is that the in-line ECC of the DRA821 would use a normal LPDDR4 device. Note that it would impact the total available space as some memory would store the ECC codes.

Best regards,
Kevin

Hi,

Apologize for the delay. Confirming that the in-line ECC of the DRA821 will work with an LPDDR4 SDRAM that does NOT have on-die ECC.

Thanks,
Kevin
