An apparatus and method for transferring signals between timing domains.
The apparatus includes a receiver for receiving signals operative in a
first timing domain, a decoder for at least partially decoding the
signals to generate at least one decoded signal, and an output timing
register for outputting the at least one decoded signal in a second
timing domain. The signals transferred from the first timing domain to
the second timing domain may include, for example, command and/or address
signals. The first and second timing domains need not have any
predetermined phase relationship. By at least partially decoding the
signals during the transfer between the first and the second timing
domains, the latency introduced by the timing domain transfer is employed
for a useful purpose.
