An integrated circuit memory device, system and method turns on an output
driver in response to a stored value that represents an amount of time
from when the output driver is in an operational state to when the output
driver begins to output valid read data in various embodiments. An output
driver outputs valid read data after a settling amount of time. The sum
of the amount of time from when the memory device receives a read command
to when the output driver is turned-on and the settling amount of time,
is approximately the time from receiving the read command, to at least
beginning to provide valid read data at the output of the integrated
circuit memory device. A read command is provided to the integrated
circuit memory device by a memory controller. In an embodiment, the
memory controller also provides or programs the value that represents the
amount of time from when the output driver is in an operational state to
when the output driver begins to output valid read data.
