  3. IDT71256L25DB STAM related

    ... last power off condition even after a power recycling.  We have come across literature describing the data remanence property and would like to understand it better. We are also curious if the phenomenon is tested by manufacturer. Could you please provide information on data remanence, especially on SRAM like 71256L25DB.
