RAS Down Mode and RAS Up Mode: With DRAM provided with fast page mode, as long as
accesses are to the same row address, burst operation can be continued without interruption even if
accesses are not consecutive by holding the RAS signal low.
• RAS Down Mode
Rev.5.00 Sep. 12, 2007 Page 156 of 764
REJ09B0396-0500
To select RAS down mode, set the BE and RDM bits to 1 in DRCRA. If access to DRAM
space is interrupted and another space is accessed, the RAS signal is held low during the
access to the other space, and burst access is performed if the row address of the next DRAM
space access is the same as the row address of the previous DRAM space access. Figure 6.21
shows an example of the timing in RAS down mode.
