Figure 4.35 Operation in Successive RAS Mode

(1) When accessing the DRAM area, an ordinary RAS cycle is executed first.
(2) If access to the same DRAM is suspended during a page mode, #RASx remains asserted while some other

device is accessed. In this case, a cycle to temporarily deassert #DRD/#DWE is inserted before accessing the
other device.

(3) If access to the same page in the same DRAM area as in (1) is requested after (2), #DRD/#DWE is asserted

back again to restart the page mode.

(4) A precharge cycle is executed when one of the following conditions that cause the page mode to suspend is

encountered:
• access to different DRAM is requested;
• access to a different page in the same DRAM area is requested;
• access to some other device than DRAM is requested;
• CAS-before-RAS refresh is requested; and
• relinquishing of bus control is requested by an external bus master.

Note: When using the successive RAS mode, always be sure to use #DRD for the read signal and #DWE

for the low-byte write signal.
