10.BURST Termination
stop command and the other is the precharge command.
10.1 BURST Stop Command
goes to high-impedance after the CAS latency from the burst stop command.
Hi-Z at the same clock with the burst stop command.
Burst Termination
Remark BST: Burst stop command
Remark BST: Burst command
There are two methods to terminate a burst operation other than using a read or a write command. One is the burst
During a read burst, when the burst stop command is issued, the burst read data are terminated and the data bus
During a write burst, when the burst stop command is issued, the burst write data are termained and data bus goes to
CAS latency=3
CAS latency=2,3
CAS latency=2
