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 truth table for the operation commands.
Notes
1.
V = Valid, x = Don’t Care, L = Low Level, H = High Level
2. CKEn signal is input level when commands are provided, CKEn-1 signal is input level one clock
before the commands are provided.
3. This is the state of the banks designated by BA0, BA1 signals.
4. Device state is Full Page Burst operation
5. Power Down Mode can not entry in the burst cycle. When this command assert in the burst mode
cycle device is clock suspend mode.
