Memory in circuit logic

Hello,
So for a project, I am attempting to make a circuit able to record some integer values (from inputs) and then make decisions based off of their values (return which input gave the highest input) .

My question is, how can I best store values with a digital logic circuit? I was thinking that I could use flip flops to store values, but I am trying to find the best way to go about this. Any suggestions?

Thanks,
James

How many is "some", so we can have an idea of how to "best store" them?
And are you looking at one set on inputs or multiple sets?
And how large are your integer inputs (how many bits are required to store and compare)?

Without specific requirements, I can think of several suggestions, none of which may be applicable.

Thanks for the replies.
I agree that a microcontroller would probably be best, but I am trying to challenge myself and see if I can do this project without one.

And I would like to store multiple 6 bit values from various inputs. However, we can simplify the process for now and assume there is only one 6 bit input.

Thanks,
James

Thanks for your input.

But as a follow up question, what are the main differences between the various kinds of flip flops (such as D-latch and SR)?
In particular, how is the one more useful than the other?

Thanks so much, you all are very helpful,
James

Which is more useful depends on the situation. The two most popular are D flip flops and JK flip flops.

Each has their own characteristics that are useful in various situations.

As someone else already said use a micro. I've been designing electronics for 40 years and in the early days logic was all we had, that was just before micros came along. I can pretty much say that in the last 10 years or more I haven't touched a logic chip, everything (other than absolutely single logic chip circuits) can be done simpler, more flexible and cheaper using a micro unless you are looking for some high speed parallel processing and even then multi-processor solutions are my first go-to.
