Operation Definition
All 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, CAS latency, burst length, and burst sequence can be programmed in the
SDRAM Mode Register. The mode set operation must be done after the initial power up and before
any activate command . Any content of the Mode Register can be altered by re-executing the mode
set command. 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.
