    * - | ``HSA_SCRATCH_SINGLE_LIMIT``
        | Specifies the threshold for the amount of scratch memory allocated and reclaimed in kernel dispatches.
        | Enabling ``HSA_NO_SCRATCH_RECLAIM`` circumvents ``HSA_SCRATCH_SINGLE_LIMIT``, and treats ``HSA_SCRATCH_SINGLE_LIMIT`` as the maximum value.
+        |
+        | **NOTE:** In the 7.0 release the developer can use the HIP enumerator ``hipExtLimitScratchCurrent`` to programmatically change the default scratch memory allocation size.
