CAM DESIGN FOR BIT STRING LOOKUP |
摘要 |
In one embodiment, a programming content addressable memory (CAM) comprising at least one match line, the at least one match line being preloaded to high, and being logically OR-ed for all selector lines the at least one match line being inverted to low upon a match result the at least one match line comprising transistors and grounding which are activated only when a stored data value and a corresponding selector line evaluate to 1 and the corresponding selector line having a logical AND with the stored data value, wherein the programming CAM is implemented as a Bit Indexed Explicit Replication (BIER) table. Related apparatus, systems and methods are also described. |

1: An apparatus comprising:
a programming content addressable memory (CAM) comprising at least one match line, the at least one match line being preloaded to high, and being logically OR-ed for all selector lines; the at least one match line being inverted to low upon a match result; the at least one match line comprising a memory cell which is activated only when a stored data value and a corresponding selector line evaluate to 1; and the corresponding selector line having a logical AND with the stored data value. |
