Synchronous Operation
11.4.4.6 Self-Refresh Operation
Self-refresh is a method of allowing the SDRAM to enter into a low-power state, while at
the same time to perform an internal refresh operation and to maintain the integrity of the
data stored in the SDRAM. The DRAM controller supports self-refresh with DCR[IS].
When IS is set, the
command is sent to the DRAM controller. Figure 11-23 shows the self-refresh operation.
11.4.5 Initialization Sequence
Synchronous DRAMs have a prescribed initialization sequence. The DRAM controller
