Full page burst is an extension of the above tables of Sequential Addressing, with the length being 256 for 1Mx16 divice.

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.

Cf.)Sequence of 4 & 5 is regardless of the order.
