Hi could someone explain to me how to access a single memory location in a microcontroller?

Which microcontroler and which language ?
School assignment ?

Memory Location

Sorry not a microprocessor. Is for any memory chip. I not sure if it would be the same for a microcprocessor. I just looking for the theory explaination on how to access a single location. Not code.

I know addess decoding logic is used to connect cells in the array(memory is an array of cells) to the addressing mechanism used (whichever mechanism used because there are many). Then memory is assigned addresses in sequential order according to the line of decoding logic its select line is connected to. Thus i can access an entire address but how do i go on to access a single memory location from that address?

It's entirely dependent on the device you're using. You should read the PDF file of a real wold memory chip similar to something you are thinking of using or want to understand. Search Digikey or some other online supplier of chips, find a chip that looks like what you're talking about and then read the PDF datasheet, it will explain everything you need to know about how to access that particular device in whatever modes it supports.

Single memroy location

Ok thanks i'm reading the 24C08 datasheet currently.

The information on how to read a single address is right in the PDF.. Read the whole thing.
