White Electronic Designs Corp. reserves the right to change products or specications without notice.
A simple algorithm for meeting both refresh and DLL
requirements is to apply NOPs for tXSNR time, then a DLL
Reset and NOPs for 200 additional clock cycles before
applying any other command.
* Self refresh available in commercial and industrial temperatures only.
