Actually, no. Memristors work by moving around oxygen atoms, and the read and write signals share wires. The write signal has to reach over the entire length of the cell, for some time, for a write to be successful. You can't even begin reading until the write has finished, and the write signal, which has orders of magnitude higher current than read, has been cleared from the wire.
