COMMAND TRUTH TABLE
Note :
1. Exiting Self Refresh occurs by asynchronously bringing CKE from low to high
2. X = Don
t care, H = Logic High, L = Logic Low. BA =Bank Address, RA = Row Address, CA = Column Address,
Opcode = Operand Code, NOP = No Operation
3. The burst read sigle write mode is entered by programming the write burst mode bit (A9) in the mode register to a logic 1.
4. This command stops a full-page burst operation, and is illegal otherwise. Full page burst continues untill this command is input.
When data input/output is completed for full-page of data, it automatically returns to the start address and input/output is performed repeatedly.
