Abstract
Embodiments of the present invention provide a memory device having multiple modes of data transfer. In one embodiment, async/sync logic and a configuration register provide for asynchronous and synchronous data transfer. The async/sync logic utilizes the configuration register and various control signals to determine whether a data transfer operation should be asynchronous or synchronous. The async/sync logic also utilizes the configuration register and various control signals to determine other functionalities of the particular data transfer mode. Functionalities may include normal and page mode, page length, bust read, linear or interleaved burst, burst wrap, burst suspend, data hold length, first access latency, transition between synchronous and asynchronous mode, and the like.
