A ternary optical processor can have thousands of data bits, each of which can be independently assigned to a different task and reconstructed in real-time according to user demand at runtime. Consequently, significant amounts of data are frequently transferred between storage and processor in a ternary optical computer. In this study, a dual-space storage (DSS) system and a new technique to push memory space (PMS) on the DSS was developed to rectify this issue. The developed methods exploit the non-volatility and random access of solid state disks. This paper introduces the theory, architecture, management, and usage of DSS in detail, and also describes the hardware structure, technical principles, and push commands of PMS. Several new methods based on the unclosable windows in DSS (such as jobs resuming as soon as the computer is powered on, elimination of the wait time to launch a program, and improved system security) are also discussed. The results of simulation of DSS and PMS in an 8086 system verify the efficacy of the new theory and the related technologies. Both DSS and PMS not only meet the memory requirements of the ternary optical computer, but also provide a theoretical and technical foundation for constructing a new computer architecture based on solid state disks.
