Patent ID: 10847224

Abstract:
Systems, devices, and methods are provided for implementing a low power and area ternary content addressable memory (TCAM). The TCAM comprises a plurality of memristor-based TCAM (mTCAM) cells, each consisting of two memristors and two transistors. The first and second memristors are connected in series, with a first end of the first memristor connected to a first data line, first end of the second memristor connected to a second data line, and the second ends of the resistors connected together at a common node. The drain of a programming transistor is connected to the common node, with the source connected to a third data line, and the gate connected to a word line. Common node is further connected to the gate of a match-line transistor, such that if a mismatch is detected common node applies a voltage to the gate to pull-down the voltage on a pre-charged match line.
