Boundary Scan
3.1
General Description
The 1-Gbit GDDR3 incorporates a modified boundary scan test mode. This mode doesn’t operate in accordance with IEEE
Standard 1149.1-1990. To save the current GDDR3 ball-out, this mode will scan the parallel data input and output the scanned
data through the WDQS0 pin controlled by SEN.
Note: Both pads bCS1 and A12 will be activated and could be accessed during Boundary Scan.
3.2
Disabling the scan feature
It is possible to operate the 1-Gbit GDDR3 without using the boundary scan feature. SEN (at U-4 of 136- ball package) should
be tied LOW(VSS) to prevent the device from entering the boundary scan mode. The other pins which are used for scan mode,
RES, MF, WDQS0 and CS will be operating at normal GDDR3 functionalities when SEN is deasserted.
TABLE 6
Boundary Scan Exit Order
Notes
1. When the device is in scan mode, the mirror function will be disabled and none of the pins are remapped.
2. Since the other input of the MUX for DM0 tied to GND, the device will output the continuous zeros after scanning a bit #67,
if the chip stays in scan shift mode.
3. An unconnected CS1 and A12 on the board will be read as undefined.
