Latest Patents
Tolman holds a patent for an anti-piracy system that utilizes separate storage and alternate execution. This system includes a random access memory (RAM) device and one or more read-only memory (ROM) devices. The RAM and ROMs are connected in parallel to a data transfer bus and an address bus. Selected proprietary portions of a program are pre-stored in the ROMs prior to distribution to system users. The remaining portions of the program are stored on an external storage medium, such as a diskette, which is accessible to system users. When the program is executed, the portion stored on the external medium is loaded into the RAM. The system executes each program instruction in the RAM until it is instructed to transfer to one of the ROMs for executing the proprietary portions. This innovative design ensures that unauthorized copies of the program will be incomplete, as the proprietary portions are maintained in the ROMs.
