摘要：
An interleave lock arrangement for a computer system ensures the atomicity of a data transfer operation over a selected bus between a selected intelligent controller and a selected memory interleave, without interfering with data transfers over unselected buses between unselected intelligent controllers and unselected memory interleaves. An interleave lock signal issued by the selected intelligent controller over the selected bus is detected by and prevents only unselected intelligent controllers on the selected bus from executing bus cycles while the interleave lock signal is being asserted.
