Claim:
1. A method for transferring data from a first semiconductor device to a second semiconductor device comprising: setting desired preamble length information in a register, wherein the desired preamble length information is a selected one of a plurality of possible preamble lengths; providing a preamble having a duration specified by the desired preamble length information followed by a toggle signal having a burst length on a data strobe terminal of the first semiconductor device; providing data in synchronization with the toggle signal on a data terminal of the first semiconductor device; receiving the preamble and the toggle signal on a data strobe terminal of the second semiconductor device; activating a gate connected to the data strobe terminal of the second semiconductor device during the preamble to provide a gated clock; and receiving the data on a data terminal of the second semiconductor device in synchronization with the gated clock.
