Abstract
We study the tolerance of data structures to memory faults. We observe that many pointer-
based data structures (e.g., linked lists, trees, etc.) are highly nonresilient to faults. A single
fault in a pointer in a linked list or a tree may result in the loss of an unproportionately large
amount of data. In this paper we present a formal framework for studying the fault-tolerance
properties of pointer-based data structures, and provide fault-tolerant versions of the stack, the
linked list, and the dictionary tree.
