A sizeable population can be found in the nearby Yargab-Chu valley in Mechuka (West Siang), where the population is around 4000 to 5000 and as well as Medog county in Tibet. The religious life of the Memba revolves around the Mechuka Gompa, similar to the Monpa of West Kameng and Tawang. Local genealogies suggested that they came from Tawang and settled in the region several centuries back.

Their homes, like most of the other Tibetan Buddhist tribes, are made of stone and wood. The house is raised above the ground and the floor and walls are made of wooden planks. Corrugated aluminum has replaced wood as aroofing material in recent years.
