Description
Input data mask: UDM is an upper-byte, input mask signal for write data. Upper-
byte input data is masked when UDM is sampled HIGH along with that input data
during a WRITE access. Although the UDM ball is input-only, the UDM loading is
designed to match that of the DQ and DQS balls. UDM is referenced to V
Data input/output: Lower byte of bidirectional data bus for the x16 configuration.
DQ[7:0] are referenced to V
Data input/output: Upper byte of bidirectional data bus for the x16 configuration.
DQ[15:8] are referenced to V
Lower byte data strobe: Output with read data. Edge-aligned with read data.
Input with write data. Center-aligned to write data.
Upper byte data strobe: Output with read data. Edge-aligned with read data.
Input with write data. DQS is center-aligned to write data.
Power supply: 1.5V ±0.075V.
DQ power supply: 1.5V ±0.075V. Isolated on the device for improved noise immunity.
Reference voltage for control, command, and address: V
maintained at all times (including self refresh) for proper device operation.
Reference voltage for data: V
refresh) for proper device operation.
Ground.
DQ ground: Isolated on the device for improved noise immunity.
External reference ball for output drive calibration: This ball is tied to an
external 240Ω resistor (RZQ), which is tied to V
No connect: These balls should be left unconnected (the ball has no connection to
the DRAM or to other balls).
