Memory in logic gates for specified time intervals

[thespaceman]

I am a physics student new to the world of electronics and I have a question that may turn out to be very simple. What I am trying to design requires that a single output given some input be held in memory for a specified time despite any differing input being sent through during that time interval. Then after the time interval the output is immediately dependent on any new input. Any suggestions would be useful.

refer to flip -flop .
it is a memory storing element formed by NOR or NAND gate .

If the input is digital that the thing you are referring to is called a latch (or flipflop).

If the input is an analog signal then the thing you're referring to is called a "sample and hold".
