Abstract
We present solutions to the problem of simulating an atomic single-reader, single-writer variable with non-atomic bits. The first construction, for the case of a 2-valued atomic variable (bit), achieves the minimal number of non-atomic bits needed. The main construction of a multi-bit variable avoids repeated writing (resp. reading) of the value in a single write (resp. read) action on the simulated atomic variable. It improves on existing solutions of that type in simplicity and in the number of non-atomic bits used, both in presence and in accesses per read/write action.
