NON-VOLATILE REGISTER AND NON-VOLATILE SHIFT REGISTER

摘要

Non-Volatile Register (NVR) and Non-Volatile Shift Register (NVSR) devices are disclosed. The innovative NVR and NVSR devices of the invention can rapidly load the stored non-volatile data in non-volatile memory elements into their correspondent static memory elements for fast and constant referencing in digital circuitry. According to the invention, the loading process from non-volatile memory to static memory is a direct process without going through the conventional procedures of accessing the non-volatile memory, sensing from the non-volatile memory, and loading into the digital registers and shift registers.
