Why do memory modules like flip-flops have a not q output and an r input?
What is the necessity of having either? In a d latch the r input is connected to the s input with an inverter, why is it necessary at all? The same goes for not q, if you really needed an inverted q output then you could just add an inverter when necessary. The only thing i could think of is that somehow these are used to connect individual modules sequentially (a 16x4 memory would have 16 rows of 4 bit words; how are the modules connected to form 1 word?)
