\begin{abstract}

Sharing data between multiple asynchronous users---each of which can
atomically read and write the data---is a feature that may help to
increase the amount of parallelism in distributed systems. An
algorithm implementing this feature is presented. The main
construction of an $n$-user atomic variable directly from
single-writer, single-reader atomic variables uses $O(n)$ control bits
and $O(n)$ accesses per Read/Write running in $O(1)$ parallel time.
