Is RAM Dedicated by Core in Mutli-Core Processor Systems?

For example, suppose your program utilizes only one core of a two or
four-core processor. Will that core have the use of all available RAM or
are large chunks reserved for the other idle cores?

Memory is assigned to programs. A program can use the amount of memory assigned to it whether is runs on one core or more that one core.
