+class _MemoryOptimizedFeedForward(torch.nn.Module):
+    r"""
+    See [`~models.attention.FeedForward`] parameter documentation. This class is a copy of the FeedForward class. The
+    only difference is that this module is optimized for memory.
+
+    This method achieves memory savings by applying the ideas of tensor-parallelism sequentially. Input projection
+    layers are split column-wise and output projection layers are split row-wise. This allows for the computation of
+    the feedforward pass to occur without ever materializing the full intermediate tensor. Typically, the intermediate
+    tensor takes 4x-8x more memory than the input tensor. This method reduces that with a small performance tradeoff.
