6, lines 61-64, of Leedy, indicating that the ECC circuitry is
among components that are conventionally part of a memory device.
It is appellants’ position that the artisan “would no sooner move
the ECC circuitry from the memory device to the data storage system
as he would move the address decoders or listed components to the
data storage system” (brief-page 9).
Claim 135 calls for a “data storage system” and “a memory
device” which are coupled to the data storage system (we note, as
did the examiner, that appellants do not appear to argue the
“releasably” coupled aspect of the claimed invention). The claim
further indicates that the data storage system comprises error
checking and correcting (ECC) functionality.
Even though the claim has two separately labeled elements,
“data storage system” and “memory device,” it is true, as the
examiner indicates at page 9 of the answer, that a “data storage
system necessarily includes storage” and a memory device is part of
a data storage system. Therefore, as the examiner states, ECC
circuitry in the memory device is also in the data storage system.
Since Leedy teaches ECC circuitry in a memory device, then it,
broadly, also teaches the use of ECC circuitry in a “data storage
system,” as claimed.
