Abstract
A ternary content addressable memory is provided comprising; a memory device that includes a plurality of memory address locations; hash logic operative to determine a hash value, based upon a ternary key, wherein the determined hash value corresponds to a memory address location of the memory device; an encoder operable to convert the ternary key to a binary bit representation; wherein converting includes determining binary mapping bits based upon number and positions of ternary non-X (don't care) value bits of the ternary key; wherein converting further includes determining a different binary data bit to correspond to each different ternary non-X value bit of the ternary key; and memory controller logic to cause the memory device to store the binary bit representation at the memory address location that corresponds to the determined hash value.
