Query: Energy-efficient stochastic computing with superparamagnetic tunnel
  junctions   Superparamagnetic tunnel junctions (SMTJs) have emerged as a competitive,
realistic nanotechnology to support novel forms of stochastic computation in
CMOS-compatible platforms. One of their applications is to generate random
bitstreams suitable for use in stochastic computing implementations. We
describe a method for digitally programmable bitstream generation based on
pre-charge sense amplifiers. This generator is significantly more energy
efficient than SMTJ-based bitstream generators that tune probabilities with
spin currents and a factor of two more efficient than related CMOS-based
implementations. The true randomness of this bitstream generator allows us to
use them as the fundamental units of a novel neural network architecture. To
take advantage of the potential savings, we codesign the algorithm with the
circuit, rather than directly transcribing a classical neural network into
hardware. The flexibility of the neural network mathematics allows us to adapt
the network to the explicitly energy efficient choices we make at the device
level. The result is a convolutional neural network design operating at
$\approx$ 150 nJ per inference with 97 % performance on MNIST -- a factor of
1.4 to 7.7 improvement in energy efficiency over comparable proposals in the
recent literature.
