Computational memory storage media has undergone revolution with time. Novel memory storage technologies include use of biological material especially proteins such as Bacteriorhodopsin. Bacteriorhodopsin (Br) has great sensitive thermal, chemical and holographic (3-D volumetric) features. Bacteriorhodopsin stores data in a 3-D matrix. Three dimensional optical memories can theoretically approach high storage densities. 3D cubes of Bacteriorhodopsin provide much more space than two dimensional optical memories. Three-dimensional optical memory devices made from Bacteriorhodopsin utilize two photon read and write-method. Hence, a good choice for developing protein based optical memory. Future memory technologies also comprise of hybrid technology that hybridizes Bacteriorhodopsin with the solid state components of a computer. In the present paper focused on computational basis for bacterio-rhodopsin optical memory, advantages and applications. This paper also focuses on various algorithms based on computational methods like – Write -data, Read- data, Erase -data and Refresh -memory with emphasis on Bacteriordopsin.
