Abstract
A memory includes a read clock state machine and a read clock driver circuit. The read clock state machine has a first input for receiving a read command signal, a second input for receiving a read clock mode signal, and an output for providing a drive enable signal. The read clock driver circuit has an output for providing a read clock signal in response to a clock signal when the drive enable signal is active. When the read clock mode signal indicates a read-only mode, the read clock state machine starts toggling the read clock signal during a read preamble period before a data transmission of a first read command, and continues toggling the read clock signal for at least a read postamble period following the data transmission of the first read command.
