A circuit includes a degeneration p-channel metal-oxide-semiconductor (PMOS) transistor, a load PMOS transistor, and a clamp transistor configured to clamp a voltage applied to a resistance based memory element during a sensing operation. A gate of the load PMOS transistor is controlled by an output of an operational amplifier.
摘要:
A resistance based memory sensing circuit has reference current transistors feeding a reference node and a read current transistor feeding a sense node, each transistor has a substrate body at a regular substrate voltage during a stand-by mode and biased during a sensing mode at a body bias voltage lower than the regular substrate voltage. In one option the body bias voltage is determined by a reference voltage on the reference node. The substrate body at the regular substrate voltage causes the transistors to have a regular threshold voltage, and the substrate body at the body bias voltage causes the transistors to have a sense mode threshold voltage, lower than the regular threshold voltage.

Systems and methods of resistance-based memory circuit parameter adjustment are disclosed. In a particular embodiment, a method of determining a set of parameters of a resistance-based memory circuit includes determining a range of sizes for a clamp transistor and selecting a set of clamp transistors having sizes within the determined range of sizes. For each clamp transistor in the set of clamp transistors, a simulation may be executed to generate a first contour graph representing current values over a range of statistical values. The first contour graph may be used to identify a read disturbance area and a design range of the gate voltage of the clamp transistor and a load of the clamp transistor. The method may execute a simulation to generate a second contour graph representing sense margin over a range of statistical values of the gate voltage of the clamp transistor and the load of the clamp transistor. A sense margin may be selected based on the second contour graph that also satisfies the design range of the first contour graph. A sense margin may be determined for a selected clamp transistor in the set of transistors and the corresponding gate voltage and the load of the selected clamp transistor is determined based on the determined sense margin.

A resistance based memory circuit is disclosed. The circuit includes a first transistor load of a data cell and a bit line adapted to detect a first logic state. The bit line is coupled to the first transistor load and coupled to a data cell having a magnetic tunnel junction (MTJ) structure. The bit line is adapted to detect data having a logic one value when the bit line has a first voltage value, and to detect data having a logic zero value when the bit line has a second voltage value. The circuit further includes a second transistor load of a reference cell. The second transistor load is coupled to the first transistor load, and the second transistor load has an associated reference voltage value. A characteristic of the first transistor load, such as transistor width, is adjustable to modify the first voltage value and the second voltage value without substantially changing the reference voltage value.

A safety razor blade tool comprises a substantially rectangular, single-edged safety razor blade having a cutting edge and an opposing non-cutting edge and a thermoplastic protective cover fixedly attached to the non-cutting edge. The protective cover is substantially coextensive with the length of the non-cutting edge of the blade and has a resilient, slip-resistant surface. The protective cover comprises two substantially identical, complimentary cover parts. Each cover part comprises an injection-molded substantially rigid inner layer of thermoplastic material and a rubberized outer layer covering the rigid inner layer. The outer layer comprises a compatible, injection-molded thermoplastic rubber.

A package for displaying a plurality of safety razors is provided which includes opposed front and rear panels articulated to one another to define an enclosure. Each of the opposed front and rear panels has an elongated slot provided therein defining a blade head maintaining area for the razors. An upper panel extends from the front panel to the rear panel above the blade head maintaining area. Structure projects into at least one of the opposed slots for inhibiting movement of the plurality of razors within the blade head maintaining area. In addition, a passageway descends from at least one of the slots in the opposed panels for permitting individual removal of the plurality of razors from the package while inhibiting the egress of the remaining razors therethrough.
摘要:
A low sensing current non volatile flip flop includes a first stage to sense a resistance difference between two magnetic tunnel junctions (MTJs) and a second stage having circuitry to amplify the output of the first stage. The output of the first stage is initially pre-charged and determined by the resistance difference of the two MTJs when the sensing operation starts. The first stage does not have a pull-up path to a source voltage (VDD), and therefore does not have a DC path from VDD to ground during the sensing operation. A slow sense enable (SE) signal slope reduces peak sensing current in the first stage. A secondary current path reduces the sensing current duration of the first stage.
