Research of RAM data remanence times

Dynamic RAM (DRAM) must be periodically refreshed to maintain its content. If any bit is inadvertently swapped, we can say that the memory doesn’t work as it should. JEDEC (Joint Electron Device Engineering Council, a body that provides DDR specification, among other things) specifies how often this has to be done to ensure proper operation. However, some people are more interested in how long the data may be preserved after DRAM is powered down.
