Operation Definition
All of SDRAM operations are defined by states of
control signals CS, RAS, CAS, WE, and DQM at the
positive edge of the clock. The following list shows
the most important operation commands.
Mode Register
For application flexibility, a CAS latency, a burst
length, and a burst sequence can be programmed in
the SDRAM mode register. The mode set operation
must be done before any activate command after
the initial power up. Any content of the mode register
can be altered by re-executing the mode set com-
mand. Both banks must be in precharged state and
CKE must be high at least one clock before the
mode set operation. After the mode register is set, a
Standby or NOP command is required. Low signals
of RAS, CAS, and WE at the positive edge of the
clock activate the mode set operation. Address input
data at this timing defines parameters to be set as
shown in the following table.
