Abstract: Disclosed is a sense amplifier which includes a pre-amplifier that is connected between an input node receiving an input signal and a first node, a second switch connected between the first node and a first output node outputting an output signal, an amplifier connected between the first output node and a second output node outputting an inverted output signal, and a second switch connected between the input node and the second output node. The pre-amplifier includes an inverter connected between the input node and the first node, and a third switch connected between the input node and the first node.

Abstract: Transistor noise tolerant, non-volatile (NV) resistance element-based static random access memory (SRAM) physically unclonable function (PUF) circuits and related systems and methods. In exemplary aspects, a transistor and its complementary transistor, such as a pull-up transistor and complement pull-down transistor or pull-down transistor and complement pull-up transistor, of the PUF circuit are replaced with passive NV resistance elements coupled to the respective output node and complement output node to enhance imbalance between cross-coupled transistors of the PUF circuit for improved PUF output reproducibility. The added passive NV resistance elements replacing pull-up or pull-down transistors in the PUF circuit reduces or eliminates transistor noise that would otherwise occur if the replaced transistors were present in the PUF circuit as a result of changes in temperature, voltage variations, and aging effect.

Abstract: Offset-cancellation sensing circuit (OCSC)-based Non-volatile (NV) memory circuits are disclosed. An OCSC-based NV memory circuit includes a latch circuit configured to latch a memory state from an input signal. The OCSC-based NV memory circuit also includes a sensing circuit that includes NV memory devices configured to store the latched memory state in the latch circuit for restoring the memory state in the latch circuit when recovering from a reduced power level in an idle mode. To avoid the need to increase transistor size in the sensing circuit to mitigate restoration degradation, the sensing circuit is also configured to cancel an offset voltage of a differential amplifier in the sensing circuit. In other exemplary aspects, the NV memory devices are included in the sensing circuit and coupled to the differential transistors as NMOS transistors in the differential amplifier, eliminating contribution of offset voltage from other differential PMOS transistors not included.

Abstract: Systems and methods relate to operations on a magnetoresistive random access memory (MRAM) bit cell using a circuit configured in multiple phases. In a sensing circuit phase, the circuit configured to determine a first differential voltage between a data voltage across the bit cell and a reference voltage. In a pre-amplifying phase, the circuit is configured to pre-amplify the first differential voltage to generate a pre-amplified differential voltage, which does not have offset voltages that may arise due to process variations. In a sense amplifier phase, the circuit is configured to amplify the pre-amplified differential voltage in a latch. Generation of the pre-amplified differential voltage cancels offset voltages which may arise in the latch. In a write phase, the circuit is further configured to write a write data value to the MRAM bit cell.

Abstract: Error detection and correction decoding apparatus performs single error correction-double error detection (SEC-DED) or double error correction-triple error detection (DEC-TED) depending on whether the data input contains a single-bit error or a multiple-bit error, to reduce power consumption and latency in case of single-bit errors and to provide powerful error correction in case of multiple-bit errors.
