After I learn about the DFF (Data Flip-Flop). I understand Flip-Flop as a device that can memorize input data at the rising or falling edge of the clock sequence.
But why call it flip-flop? Why not something like edge-triggered memory circuit. It's kind of a nick name which is hard to get for a non-English speaker. And in my country, the translated version is kind of twisted.
Could anyone explain the reason of the naming in plain English? Thanks.
