A system and apparatus for controlling a burst sequence in a synchronous memory is described. In one embodiment, the system comprises a synchronous memory and a burst read device coupled to the synchronous memory. In one embodiment, the burst read device is configured to sense a page of data as a current page from the synchronous memory, wherein the current page contains a fixed number of words of data. The device is further configured to latch the current page of data, and synchronously read the current page of data, one word at a time. In an alternate embodiment, the burst read device further comprises a wrap-bit. If the wrap-bit is not set, the burst read device is configured to latch the current page of data, adjust a word pointer to indicate a next word of data, and repeat latching and adjusting in a sequential burst read order. If the wrap-bit is set, the burst read device is configured to latch the current page of data, adjust a word pointer to indicate a next word of data, and repeat latching and adjusting in a non-sequential burst read order.
