Hi @GlenLee,
As parallel nvSRAM parts operate at lower frequencies and have a simple parallel interface, we don't have a doc specifying the guidelines.
However, for NVSRAM parts, we recommend the following:
> Length matching should be done, and the maximum difference allowed is 1 inch.
> Decoupling capacitors should be placed on power supply lines.
> A pull-up resistor should be placed on either the CE# or WE# line.
> We recommend performing signal integrity simulations using IBIS models and adding series or parallel termination resistances if required.
Thanks,
Ritwick

Hi Ritwick,
Could we let customer refer SRAM Board Design Guidelines ?
Is should be similar ?

Hi @GlenLee,
Yes, the customer can refer to that whitepaper, but please ask them to take into account the above-mentioned points.
Thanks,
Ritwick
