    Abstract: An adjustable write pulse generator is disclosed. The adjustable write pulse generator includes a band-gap reference current, a programmable ring oscillator, a frequency divider and a single pulse generator. The band-gap reference current circuit generates a well-compensated current over a predetermined range of temperatures needed to program a chalcogenide memory cell. The programmable ring oscillator generates a first set of continuous write “0” and write “1” pulse signals based on the well-compensated current. The frequency divider then divides the first set of continuous write “0” and write “1” pulse signals into a second set of continuous write “0” and write “1” pulse signals. The single pulse generator subsequently converts the second set of continuous write “0” and write “1” pulse signals into a single write “0” pulse signal or a single write “1” pulse signal when programming the chalcogenide memory cell.

    Abstract: A non-volatile single-event upset (SEU) tolerant latch is disclosed. The non-volatile SEU tolerant latch includes a first and second inverters connected to each other in a cross-coupled manner. The gates of transistors within the first inverter are connected to the drains of transistors within the second inverter via a first feedback resistor. Similarly, the gates of transistors within the second inverter are connected to the drains of transistors within the first inverter via a second feedback resistor. The non-volatile SEU tolerant latch also includes a pair of chalcogenide memory elements connected to the inverters for storing information.

    Abstract: A current mode logic voter circuit includes three two-input split NOR gates. Each two-input split NOR gate receives a corresponding pair of input signals and generates a pair of first output signals responsive to the input signals. A three input split NOR gate is coupled to the two-input split NOR gates to receive the first output signals and generates a second pair of output signals responsive to the first output signals from the two-input split NOR gates. The two and three-input split NOR gates can be formed from current mode logic buffer circuits, and in one embodiment in the three-input split NOR gate the buffer circuits are hardened.

    Abstract: Techniques described herein are generally related to steganalysis of suspect media. Steganalysis techniques may include receiving instances of suspect media as input for steganalytic processing. A first set of quantized blocks of data elements may be identified within the media, with this first set of blocks being eligible to be embedded with steganographic data. A second set of quantized blocks of data elements may be identified within the media, with this second set of blocks being ineligible to be embedded with steganographic data. The steganalysis techniques may requantize the first and second blocks. In turn, these techniques may compare statistics resulting from requantizing the first block with statistics resulting from requantizing the second block. The steganalysis techniques may then assess whether the first block of data elements is embedded with steganographic features based on how the statistics of the second blocks compare with the statistics of the first blocks.

    Abstract: An analog access circuit for characterizing chalcogenide memory cells is disclosed. The analog access circuit includes an analog access control module, an address and data control module, and an analog cell access and current monitoring module. The analog access control module selectively controls whether a normal memory access or an analog memory access should be performed on a specific chalcogenide memory cell. The address and data control module allows a normal memory access to the chalcogenide memory cell according to an input address. The analog cell access and current monitoring module performs an analog memory access to the chalcogenide memory cell according to the input address, and monitors a reference current from a sense amplifier associated with the chalcogenide memory cell.
