PREHEAT oven to 325°F if using a silver 9-inch springform pan (or to 300°F if using a dark nonstick 9-inch springform pan). Place 30 of the cookies in resealable plastic bag. Flatten bag to remove excess air, then seal bag. Finely crush cookies by rolling a rolling pin across the bag. Place in bowl. Add butter; mix well. Press firmly onto bottom of pan.
BEAT cream cheese, sugar and vanilla in large bowl with electric mixer on medium speed until well blended. Add sour cream; mix well. Add eggs, 1 at a time, beating just until blended after each addition. Chop or crush remaining cookies. Gently stir 1-1/2 cups of the chopped cookies into cream cheese batter. Pour over crust; sprinkle with the remaining chopped cookies.
BAKE 1 hour and 10 min. or until center is almost set. Cool. Refrigerate 3 hours or overnight. Cut into 16 pieces. Store leftover cheesecake in refrigerator.
