ELi5:why do memories(SRAM/DRAM) need continuous refreshing to store a bit of information?
In: Engineering
The issue is that the charge placed into the tiny capacitors that store the bits will slowly leak off (I say “slowly”, it is refeshed about every 64 milliseconds). The insulation of the capacitors isn’t perfect and charge cannot be stored forever on its own. There is a tradeoff between long storage times without access to power, and rapid access with frequent changes not wearing it out.
