Specifications cited are subject to change without notice. For latest documentation see http://www.gsitechnology.com.
Note:
There are pull-up devices on the ZQ, SCD, and FT pins and a pull-down device on the ZZ pin, so those input pins can be unconnected and the
chip will operate in the default states as specified in the above tables.
