1. A method for memory management at a wireless communication device, comprising:
determining a configuration for a memory component of the wireless communication device, the configuration indicating a plurality of processors that share the memory component and indicating one or more permissions for a first memory resource of the memory component;
allocating a second memory resource of the memory component by allocating a sub-region of the first memory resource to the second memory resource, wherein the second memory resource is writable by the plurality of processors;
assigning, to a first processor of the plurality of processors, a permission to write to the second memory resource based at least in part on allocating the sub-region of the first memory resource to the second memory resource; and
preventing a second processor of the plurality of processors from writing to the second memory resource based at least in part on the assigned permission to the first processor.
