A memory device is provided. The memory device includes a preamble disable memory and a memory controller. The preamble disable memory is arranged to store preamble disable data. The preamble disable data includes an indication as to whether a read preamble should be enabled or disabled. In response to a read command, if the preamble disable data includes an indication that the read preamble should be enabled, the memory controller provides the read preamble. Alternatively, in response to the read command, if the preamble disable data includes an indication that the read preamble should be disabled, the memory controller disables the read preamble.
