Converting an XY TCAM to a value TCAM

摘要

Approaches for an integrated circuit ternary content addressable memory (TCAM) are provided. A system includes an array of XY TCAM cells and respective translation circuits connected to respective pairs of the XY TCAM cells. The system also includes a memory controller structured to provide control signals to the respective translation circuits. The memory controller and respective translation circuits are structured to control the array of XY TCAM cells to perform single cycle update and single cycle search operations.

1. An integrated circuit ternary content addressable memory (TCAM) system, comprising:
an array of XY TCAM cells, wherein each one of the XY TCAM cells comprises a first cell and a second cell that are connected to and share a common bit line; respective translation circuits connected to respective pairs of the XY TCAM cells; and a memory controller structured to provide control signals to the respective translation circuits, wherein the memory controller and respective translation circuits are structured to control the array of XY TCAM cells to perform single cycle update and single cycle search operations.
