Figure 13.39 Basic Timing of a Burst Read from Synchronous DRAM (Burst Length = 8)

In a cycle of access to synchronous DRAM, the BS signal is asserted for one clock cycle at the

beginning of a bus cycle. Data are accessed in the following sequence: in the fill operation for

a cache miss, the data between the 32-bit boundaries that include the missed data are first read;

after that, the data between 32-byte boundaries that include the missed data are read in a

wraparound way.
