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 thruth 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.
These are state of bank designated by BS0, BS1 signals.
4.
Power Down Mode can not entry in the burst cycle.
