    摘要: A voltage regulator for low power operation of digital circuits includes an output node for providing a regulated output voltage, a diode-connected P-channel transistor in series with a second diode-connected N-channel transistor coupled between the output node and ground, and a bias current having a value for biasing the first and second diode-connected transistors in a sub-threshold mode of operation. The low power voltage regulator further includes a buffer amplifier or emitter or source follower stage to provide a low impedance regulated voltage. The bias current may be generated by a bandgap circuit.

    摘要: A stack processor using a ferroelectric random access memory (F-RAM) for code space and a portion of the stack memory space. By storing some of the associated stacks in complementary metal oxide semiconductor (CMOS) or other volatile memory, read/write operations to only F-RAM would be obviated. As compared to an all F-RAM stack implementation, a faster, less power consuming and faster program execution time is provided. Firmware code can also be provided that will tend to concentrate the more intensive calculations to that part of the stack that is in volatile memory and minimize POP/PUSH operations to the F-RAM portion of the stack. Moreover, since only the top of the stack is maintained in volatile memory, most of it remains in F-RAM which means the application can still benefit from the high F-RAM endurance and shorter power-down times.

    摘要: An F-RAM authenticating memory device and method providing secure mutual authentication between a Host system and a memory in order to gain read/write access to the F-RAM user memory contents. The device and technique of the present invention uses an Advanced Encryption Standard AES128 encryption module in conjunction with a true hardware random number generator and basic exclusive OR (XOR) functions in order to achieve a secure algorithm with a relatively small amount of processing. Due to inherently faster write times than that of conventional floating gate non-volatile memory technologies, the use of F-RAM significantly reduces the time available to interfere with a critical security parameter (CSP) update. Moreover, unlike floating gate technologies, F-RAM's read vs. write current signature is balanced making it less prone to side channel attacks while also providing relatively faster erase times.

    摘要: A cross-coupled sense amplifier includes a voltage-compensating balancing resistor serially connected between the drain of one of the P-channel transistors in the sense amplifier and the corresponding sensing/bit line node. The value of the balancing resistor is optimized so that the voltage imbalance between the P-channel transistor is minimized and sense amplifier sensitivity is maximized. A balancing resistor can also be placed in the N-channel transistors in the sense amplifier if desired. The balancing resistor in a typical application is about 100 to 200 ohms and fabricated from polysilicon.
