  We propose a novel scheme to realize electrically controlled quantum memories
in the opto- and electro-mechanical (OEM) cavity. Combining this OEM cavity
with the mechanism of Electromagnetically Induced Transparency (EIT) we find
that the quantum interference, arising from the two optical transitions of the
$\Lambda$ type three-level atomic ensembles, can be manipulated electrically.
Numerical calculations show that the probe photon state can be well stored into
the atomic spin state by sending an electric current pulse and retrieved with
time-reverse symmetry by sending the other current pulse with opposite
direction. The quantum interference with electric controlling is expected to
apply to other quantum control aspects.
