W11

The Cell Buffer SDRAM Address (CBA[11:0])

signals identify the row address (CBA[11:0]) and

column address (CBA[7:0]) for the locations

accessed.

The CBA[11:0] output is updated on the rising edge

of SYSCLK.

CBBS[1]

CBBS[0]

Output

W12

AA12

The Cell Buffer SDRAM Bank Select (CBBS[1:0])

signals determine which bank of a dual/quad bank

Cell Buffer SDRAM chip is active. CBBS is

generated along with the row address when

CBRASB is asserted low.

The CBBS[1:0] outputs are updated on the rising

edge of SYSCLK.

CBDQM

Output

Y12

The Cell Buffer SDRAM Input/Output Data Mask

(CBDQM) signal is held high until the SDRAM

initialization is complete and then set low for normal

operation.

The CBDQM output is updated on the rising edge of

SYSCLK.
