Should we design with DDR package skew in mind ?

Hi all,

Let me confirm about designing LPDDR4.

Is it necessary to design considering the package wiring length of LPDDR4 memory ?

Hello,

  According to i.MX8M (m/n) Hardware Developer’s Guide(s):
When performing the required delay matching for LPDDR4/DDR4 routing, the bond wires within the
i.MX 8M  package need to be accounted for and included in the match calculation.

Yuri.

Thank you for quick reply.

How about the internal delay of LPDDR4 package ?

Do we need to consider it ?
