Note:
This Functional Block Diagram is intended to facilitate user understanding of the operation of
the device; it does not represent an actual circuit implementation.
Note:
DM is a unidirectional signal (input only), but is internally loaded to match the load of the bidi-
rectional DQ and DQS signals.
