According to one embodiment, a combination is comprised of a plurality of
sense amps, each having an input for receiving a clock signal. A data bus
is for receiving data from the plurality of sense amps in response to a
clock signal being input to the plurality of sense amps. A tracking
circuit is responsive to the clock signal for producing a control signal.
A plurality of latches is responsive to the control signal for latching
data from the bus. The control signal has a delay that is equal to the
time needed for a last data bit to arrive at the plurality of latches.
That delay may be equal to a delay associated with inputting the clock
signal to a last one of the plurality of sense amps, plus a delay of the
last sense amp, plus a delay of the data bus. That amount of delay may be
achieved in a number of ways which combines electrical delay with delay
inherently associated with the tracking circuit's location. For example,
the delay of the control signal may be achieved by locating the tracking
circuit proximate to the last one of the plurality of sense amps and
providing the tracking circuit with an electrical delay equal to the
delay of the last one of the plurality of sense amps. Because of the
rules governing abstracts, this abstract should not be used to construe
the claims.
