The deep power down mode is an unique function on Low Power SDRAM devices with extremely low current
consumption. Deep power down mode is entered using the BURST TERMINATE command (cf.
that CKE is LOW. All internal voltage generators inside the device are stopped and all memory data is lost in this
mode. To enter the deep power down mode all banks must be precharged.
The deep power down mode is asynchronously exited by asserting CKE HIGH. After the exit, the same command
sequence as for power-up initialization, including the 200µs initial pause, has to be applied before any other
command may be issued (cf.
