Potential for enlarging DNA memory: the validity of experimental operations of scaled-up nested primer molecular memory.
DNA is an attractive memory unit because of its immense information density. Here, we describe a memory model made of DNA, called Nested Primer Molecular Memory (NPMM). NPMM consists of many DNA strands, and each DNA strand consists of two areas: a data area and a data address area. When the address of target data is specified, only the target data can be extracted from NPMM. In this paper, we evaluate the validity of the basic operations of NPMM and then discuss the feasibility of scaled-up NPMM through some laboratory experiments. In the latter, we deal with scaled-up NPMM simulated by the Concentration Scaling method.
