Abstract
Memristor-aided logic (MAGIC) design style holds
a high promise for realizing digital logic-in-memory functionality. The ability to implement a specific gate in a MAGIC
design style hinges on the SET-to-RESET threshold ratio. The
TaOx memristive devices exhibit distinct SET-to-RESET ratios,
enabling the implementation of OR and NOT operations. As
the adoption of the MAGIC design style gains momentum,
it becomes crucial to understand the breakdown of energy
consumption in the various phases of its operation. This paper
presents experimental demonstrations of the OR and NOT gates
on a 1T1R crossbar array. Additionally, it provides insights
into the energy distribution for performing these operations
at different stages. Through our experiments across different
gates, we found that the energy consumption is dominated by
initialization in the MAGIC design style. The energy split-up is
14.8%, 85%, and 0.2% for execution, initialization, and read
operations respectively
