ABSTRACT = {We consider the static dictionary problem of using $O(n)$ $w$-bit words to store $n$ $w$-bit keys for fast retrieval on a $w$-bit \ACz\ RAM, i.e., on a RAM with a word length of $w$ bits whose instruction set is arbitrary, except that each instruction must be realizable through an unbounded-fanin circuit of constant depth and $w^{O(1)}$ size, and that the instruction set must be finite and independent of the keys stored. We improve the best known upper bounds for moderate values of~$w$ relative to $n$. If ${w/{\log n}}=(\log\log n)^{O(1)}$, query time $(\log\log\log n)^{O(1)}$ is achieved, and if additionally ${w/{\log n}}\ge(\log\log n)^{1+\epsilon}$ for some fixed $\epsilon>0$, the query time is constant. For both of these special cases, the best previous upper bound was $O(\log\log n)$.},
