command (row address MA[10:0]) and READ/WRITE command
(column address MA[7:0], with MA10 defining AUTO
PRECHARGE) to select one location out of the 521K available
in the respective bank. MA10 is sampled during a
PRECHARGE command to determine if all banks are to be
precharged (MA10 HIGH).
BA
78
O
EDO DRAM: Not used.
SDRAM: Bank Address Input. BA defines to which internal bank
the ACTIVE, READ, WRITE or PRECHARGE command is
being applied. BA is also used to program the 12th bit of the
Mode Register.
RAS[1:0]#
CS[1:0]#
80, 81
O
EDO DRAM: Row Address Strobes.
SDRAM: Chip Select. CS# enables the command decoder for
the SDRAM.
CAS[1:0]#
DQM[1:0]
89, 90
O
EDO DRAM: Column Address Strobes.
SDRAM: Input/Output Mask. DQM[1:0] are input mask signals
for write accesses and output enable signals for read accesses.
DQM0 corresponds to MD[7:0]; DQM1 corresponds to
MD[15:8].
OE#
CKE
84
O
EDO DRAM: Output Enable.
SDRAM: Clock Enable. CKE activates the SMCLK signal. The
SDRAM enters precharge power-down to deactivate the input
and output buffers, excluding CKE, for maximum power saving
when CKE is LOW coincident with a NOP.
WE#
88
O
EDO DRAM: Write Enable.
SDRAM: Command Input. SRAS#, SCAS#, and WE# (along
with CS#) define the command being entered.
SRAS#
82
O
EDO DRAM: Not used.
SDRAM: Command Input. SRAS#, SCAS#, and WE# (along
with CS#) define the command being entered.
SCAS#
85
O
EDO DRAM: Not used.
SDRAM: Command Input. SRAS#, SCAS#, and WE# (along
with CS#) define the command being entered.
SMCLK

EDO DRAM: Not used.
SDRAM: Clock.
