Are you sure it's a problem? You're probably looking at memory allocation, not memory utilization.
Try the following:
[bigip-01:Changes Pending] ~ free -m
total used free shared buffers cached
Mem: 16077 16010 66 0 365 4079
-/+ buffers/cache: 11566 4510
From the command above, it looks as if nearly 100% memory is used but in reality only 11566 MB out of 16077 MB are allocated to buffers. That's about 72% true memory usage and not 100%

Can you add a new blade? That perhaps may be the easiest option.
Your other options come down to configuration optimization (less memory allocation for caching, reduction of idle timeout values etc.). If you run your LTMs as vCMP guests, you may be able to just allocate more memory from the pool of physical memory that is available. For that, the Guest must be shut down, and new provisioning must be made on the Host system. This may help you get started: https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/vcmp_admin_11_0_0/7.html
