die-top view if all sides of the device support external memory interfaces.
The DLL can access the two adjacent sides from its location within the device. For
example, DLL0 on the top left of the device can access the top side (I/O banks 7A, 7B,
7C, 8A, 8B, and 8C) and the left side of the device (I/O banks 1A, 1B, 1C, 2A, 2B, and
2C). This means that each I/O bank is accessible by two DLLs, giving more flexibility
to create multiple frequencies and multiple-type interfaces. You can have two
different interfaces with the same frequency on the two sides adjacent to a DLL, where
the DLL controls the DQS delay settings for both interfaces.
Each bank can use settings from either or both DLLs the bank is adjacent to. For
example, DQS1L can get its phase-shift settings from DLL0, while DQS2L can get its
phase-shift settings from DLL1.
