TCAM STRUCTURES WITH REDUCED POWER SUPPLY NOISE |
| 摘要 |
A ternary content addressable memory (TCAM) structure may activate individual groups of subarrays in the TCAM structure, during a non-search mode, at configurable intervals of time. The activating causes the TCAM structure to select locations and sequences in which subarrays of the TCAM structure are activated or deactivated. When activating, the TCAM structure is configured to perform a dummy search within the particular subarray. The activating reduces a change in current during transition between a search mode and the non-search mode. |

1. A method comprising:
activating a first group of subarrays of a ternary content addressable memory (TCAM) device during a non-search mode of the TCAM by performing a dummy search within the first group of subarrays; and activating a second group of subarrays of the TCAM device during the non-search mode of the TCAM device by performing the dummy search within the second group of subarrays, wherein the activation of the first and second group of subarrays are provided in a sequential order and reduce a change in current during transition between a search mode and the non-search mode. |
