Deep Power-Down

Deep power-down mode is a maximum power-saving feature achieved by shutting off
the power to the entire device memory array. Data on the memory array will not be re-
tained after deep power-down mode is executed. Deep power-down mode is entered by
having all banks idle, with CS# and WE# held LOW with RAS# and CAS# HIGH at the
rising edge of the clock, while CKE is LOW. CKE must be held LOW during deep power-
down.
To exit deep power-down mode, CKE must be asserted HIGH. Upon exiting deep power-
down mode, a full initialization sequence is required.
