Burst Length and Sequence
(Burst of Two)
(Burst of Four)
(Burst of Eight)
POWER UP SEQUENCE
1.Apply power and start clock, attempt to maintain CKE= “H”, L(U)DQM = “H” and the other pin are NOP condition at the inputs.
2.Maintain stable power, stable clock and NOP input condition for a minimum of 200us.
3.Issue precharge commands for all banks of the devices.
4.Issue 2 or more auto-refresh commands.
5.Issue mode register set command to initialize the mode register.
6.Issue an extended mode register set command to define special function of the device after normal MRS.
Cf.)Sequence of 4~6 is regardless of the order.
