-Manipulate Managed C Memory from Java
--------------------------------------

-The Core Engine allows to expose Managed C memory to Java code. A Managed C module contains 
-at most one memory. This Managed C module memory is automatically generated by the C compiler 
-according to C source code and C compiler options. On Java side, Managed C module memory can be seen by
-using ``@WasmMemory`` annotation on a Java static byte array field declaration (mapping automatically 
-done by the :ref:`soar`).
+Access Managed C Memory from Java
+---------------------------------
+
+The Managed C memory is composed of all static arrays, structures, globals declared in C files, thread stacks and optional heap for dynamic allocations. 
+All these elements are :ref:`linked <managedc.link.module>` to the :ref:`Wasm module linear memory <managedc.linear.memory>`.
+
+On Java side, the Wasm module linear memory can be bound to a Java static byte array field declaration using the ``@WasmMemory`` annotation.
 
 .. note:: 
    A SOAR error will occurred if ``@WasmMemory`` is not strictly followed by a Java static byte array declaration (see :ref:`managedc.troubleshooting`).
