Abstract
a content addressable memory circuit is provided that includes a memory array that includes multiple memory devices that include memory locations that share a memory address and are coupled for simultaneous access. Hash logic is operative to use modulo math to determine a memory address based upon non-X values within an IP address key. Memory controller logic is operative to cause a memory device in the memory array to store the received IP address key in a memory location at the determined memory address, in a format that includes a field-size value indicative of a number of non-X values within a received IP address key and that includes non-X values within the received IP address key.
