CONTENT ADDRESSABLE MEMORY DESIGN |
摘要 |
A static CAM includes a plurality of entries E each including a number of CAM cells B and a summary S. Each CAM cell B is associated with a memory cell M and a comparator C. Generally, the CAM receives as input i number of lookup data lines. When data is received, memory cells M provide compared data for corresponding comparators C in CAM cells B to compare the compared data to the received data. If all compared data match all received data lines for an entry, then there is a hit for that entry. But if any compared data does not match the corresponding data line, then there is a miss for that line and therefore a miss for that entry. Depending on applications, the CAM returns an address if there is a hit for one or a plurality of entries.
