AMD’s Burst mode 32 Mbit and 64 Mbit 1.8 Volt devices, the Am29BDS323 and Am29BDS643 respectively, offer improvements in system speed and performance by reducing sequential read access times. Burst read capability offers an average access time reduction of more than 60 percent for an eight-word sequential read at 40 MHz compared to when the device is not used in Burst mode (asynchronous read). The total time to access eight words in asynchronous mode (non-Burst) is much longer than the Burst mode read time, which comprises an initial synchronous random access for the first word and then seven very fast Burst read times. The Am29BDS323 provides an average Burst access of 20ns with an initial synchronous access times of 120ns, while the Am29BDS643 offers an average Burst access time of 13.5ns with an initial synchronous access time of 106ns. The Am29BDS323 and Am29BDS643 Burst mode devices also provide convenient interfacing with Burst mode processors like the PowerPC, Coldfire, 68K, MIPS and Tri-core.
