Notes:
Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This
is a stress rating only, and functional operation of the device at these or any other conditions above those indicated in the
operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods
may affect reliability.

Notes:
1. Measured between V IH (DC), V IL (DC), and V IL (DC), V IH (DC).
2. DQS, DQ, and DM input slew rate is specified to prevent double clocking of data and preserve setup and hold times.
Signal transition through the DC region must be monotonic.

2. Although DM is an input-only pin, the input capacitance of this pin must model the input capacitance of the DQ and DQS pins.
This is required to match input propagation times of DQ, DQS and DM in the system.
