even wikipedia mentions that memoization is a separat feature from thunk

https://en.wikipedia.org/wiki/Thunk

   Compilers for these languages, such as the Glasgow Haskell Compiler,
   have relied heavily on thunks, with the added feature that the thunks
   save their initial result so that they can avoid recalculating it;[5]
   this is known as memoization or call-by-need.
