Description
CKEB/MAA1
O
3.3 V
SDRAM Clock Enable (SDRAM) (second copy).
SDRAM
clock enable pin.
When this signal is negated, SDRAM enters into power down mode. Note that
this signal is not implemented in the “Suspend Well” and should not be used if
suspend to RAM (STR) is implemented. This signal is also muxed to provide a
second copy of memory address MA1 (MAA1). The MA function is selected via
DRT[bit2] (offset 67h).
MTXC negates CKE (and CKEB) when SUSSTAT1# is asserted. Note that
MTXC asserts CKE (and CKEB) for all rows (i.e., CKE and CKEB cannot be
selectively asserted for certain rows and negated for other rows).

3.3V/5V
Memory Data.
These signals are connected to the DRAM data bus. These
signals have internal pull-down resistors
