Figure 10.31 Basic Timing of a Burst Read from Synchronous DRAM (Burst Length = 8)
Figure 10.31 shows an example of the basic timing of a burst-read. To allow the connection of
a lower-speed DRAM, the bits in WCR2 and MCR can be set to increase the number of cycles.
Bits RCD1 and RCD0 in MCR can be used to specify the number of cycles from the ACTV
command output cycle Tr to the READA command output cycle Tc1, where setting values of
1, 2, or 3 correspond to 2, 3, or 4 cycles, respectively. When two or more cycles are specified,
the Trw cycle for issuing of NOP commands to the synchronous DRAM is inserted between
the Tr and Tc cycles. Bits A2W2 to A2W0 and A3W2 to A3W0 in WCR2 can be used to set
the number of cycles from the READA command output cycle Tc1 to cycle Td1 where the first
read data is received. The number of cycles from 1 to 5 is specifiable independently for areas 2
and 3. Note that this number of cycles is equal to the number of CAS latency cycles of the
synchronous DRAM.
