Abstract: The invention relates to an apparatus for searching for logical address ranges of host commands. The first comparator outputs logic “0” to the NOR gate when a first end logical address is not smaller than a second start logical address. The second comparator outputs logic “0” to the NOR gate when a second end logical address is not smaller than a first start logical address. The NOR gate outputs logic “1” to a matching register and an output circuitry when receiving logic “0” from both the first and the second comparators. The output circuitry outputs a memory address of a random access memory (RAM) storing a second logical address range from the second start logical address to the second end logical address to a resulting address register when receiving logic “1” from the NOR gate.
