| This can be used for overriding the default FCRAM [[Memory_layout|memory-regions]] allocation sizes(APPLICATION, SYSTEM, and BASE). The values for this is the same as [[Configuration_Memory#APPMEMTYPE|Configmem-APPMEMTYPE]]. Values 0-1 are handled the same way by the kernel. However for NS, 0=titleinfo structure for launching a title isn't set, while non-zero=titleinfo structure is set.
