Figure 9-14
(T1), the SDRAM writes all of its on-chip RAM page buffers back into the SDRAM array. The SDTR[RP]
value determines the number of dead cycles after a precharge. Note that auto refresh occurs in T3.
SDTR[RC] determines the number of clock cycles the SDRAM remains in refresh state, during which time
it cannot accept other commands.
