memchunkhdr = a data structure describing chunks of memory allocated by the ARM11 kernel.


Here is some code describing the layout of a memory chunk header.
This is the header that the kernel uses to implement the FCRAM heap.


    struct MemoryChunkHeader {
Size : 0xC bytes?
        int num_pages; // size of this chunk in terms of small pages
        void* next;
        void* prev;
        int unk1;
        int unk2;
    };


The "next" and "prev" members are used to implement a linked-list. In fact, chances are this is actually a kernel object inherited from [[KLinkedList]].
