 ## Stack memory
 
-Similarly to the [[Stacks|stacks]], it works on the basis of LIFO: the last item
-put on the stack is the first item to be withdrawn.

 Note, this doesn't mean that the data at the memory addresses that comprise the
 stack can _only_ be accessed in a LIFO manner. Any item currently on the stack
 can be accessed (be read or modified) at any time. LIFO applies when it is is
-time to clear memory from the stack: the most recent addition is cleared first.

 ### Stack pointer
 
 A **stack pointer** is used to manage the items in the stack. This value is
-stored in a [[processor register]] and its value is the memory address of the
-item currently on the top of the stack.
