Appeal No. 2004-0940
Application No. 09/908,146
which is coupled to a requesting device before the requested data
is captured. To address the potential data corruption problem, a
masking circuit is provided which allows passage of the strobe
signal in response to a reset signal generated by a memory
controller, but subsequently blocks the strobe signals before the
strobe signal enters the tristate phase.
Claim 1 is illustrative of the invention and reads as
follows:
1. A data transfer subsystem configured to control passage
of data through a data transfer gate in communication with a
requesting device in a processor-based system, including:
data transfer logic configured to generate a data
transfer command in response to a data transfer request by
the requesting device;
data mask logic configured to generate an end of
transfer command upon completion of the data transfer; and
a masking module coupled to a data strobe input of the
data transfer gate, wherein the masking module is configured
to mask a data strobe signal conveyed to the data strobe
input responsive to the data mask logic generating the end
of transfer command.
The Examiner relies on the following prior art:

Claims 1-22, 24, and 25, all of the appealed claims, stand
finally rejected under 35 U.S.C. § 102(b) as being anticipated by
Ooishi.
