10.11 Seamless burst read operation: RL = 5 ( AL = 2, and CL = 3, BL = 4)
Note:
The seamless burst read operation is supported by enabling a read command at every other clock for BL = 4 operation, and
every 4 clock for BL = 8 operation. This operation is allowed regardless of same or different banks as long as the banks are
activated.
10.12 Seamless burst write operation: RL = 5 ( WL = 4, BL = 4)
Note:
The seamless burst write operation is supported by enabling a write command every other clock for BL = 4 operation, every four
clocks for BL = 8 operation. This operation is allowed regardless of same or different banks as long as the banks are activated.
