Figure 24
RL = 5, AL = 2, CL = 3, BL = 4
The seamless read operation is supported by enabling a read command at every BL / 2 number of clocks. This
operation is allowed regardless of same or different banks as long as the banks are activated.
Figure 25
RL = 3, AL = 0, CL = 3, BL = 8 (non interrupting)
The seamless, non interrupting 8-bit read operation is supported by enabling a read command at every BL/2
number of clocks. This operation is allowed regardless of same or different banks as long as the banks are
activated.
