Considered a sequential collection, a stack has one end which is the only position at which the push and pop operations may occur, the top of the stack, and is fixed at the other end, the bottom. A stack may be implemented as, for example, a singly linked list with a pointer to the top element. A stack may be implemented to have a bounded capacity.

If a region of memory lies on the thread's stack, that memory is said to have been allocated on the stack, i.e. stack-based memory allocation (SBMA).
The top of stack address register and the N top of stack data buffers are built from separate individual register circuits, with separate adders and ad hoc connections. However, most stack machines are built from larger circuit components where the N data buffers are stored together within a register file and share read/write buses.
