    Abstract: 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.

    Abstract: A 10T NVSRAM cell is provided with a bottom HV NMOS Select transistor in each 3T FString removed from traditional 12T NVSRAM cell. A Recall operation by reading a stored ΔVt state of flash transistors into each SRAM cell uses a charge-sensing scheme rather than the current-sensing scheme, with all other key operations unchanged. The Recall operation works under any ramping rate of SRAM's power line voltage and Flash gate signal which can be set higher than only Vt0 or both Vt0 and Vt1. Alternatively, the Store operation can use a current charging scheme from a Fpower line to the paired Q and QB nodes of each SRAM cell through a paired Flash Voltage Follower that stored ΔVtp≧1.0V. The Recall operation in this alternative embodiment is to use a 7-step approach with the FN-channel erase, FN-channel program and FN-edge program schemes, including 2-step SRAM amplification.

    Abstract: To propose a non-volatile semiconductor memory device capable of injecting charge into a floating gate by source side injection even in a single-layer gate structure. In a non-volatile semiconductor memory device (1), while each of the memory transistor (MGA1) and the switch transistor (SGA) is made to have a single-layer gate structure, when a selected memory cell (3a) is turned on by applying a high voltage to one end of a memory transistor (MGA1) from a source line (SL) during data programming and applying a low voltage to one end of the switch transistor (SGA) from a bit line (BL1), a voltage drop occurs in a low-concentration impurity extension region (ET2) in the memory transistor (MGA1) between the source line (SL) and the bit line (BL1) to generate an intense electric field, and charge can be injected into the floating gate (FG) by source side injection using the intense electric field.

    Abstract: Nonvolatile storage with long memory endurance having the advantages of easy manufacturability is obtained by using a memory cell having an information storage element including a ferroelectric material, and operating the memory cell in a volatile operating mode and a nonvolatile operating mode. The option of operating the memory cell in the volatile operating mode enables the associated advantages of high memory speed at long endurance, wherein, however, the option of operating the memory cell in the nonvolatile operating mode can bridge gaps in the power supply.
