Differential pair sense amplifier for a robust reading scheme for memristor-based memories

Memristors-based memories utilize the memristor´s resistance programmability and small structure to realize high density non-volatile memories. This programmability arises from the dependence of the memristor´s resistance on the magnetic flux and total charge, rather than the voltage and current passing through it. However, a critical requirement in memory applications is that the reading scheme should preserve the memristor state after the read. In this paper, we propose a robust reading scheme for memristor-based memories that uses a differential pair sensing amplifier.
