The invention relates to methods and systems for reading a memory cell and in particular, an STT MRAM. In accordance with one aspect of the invention, a method for reading a memory cell includes combining a cell current from a memory cell with a reference current from a reference source to create an average current, enabling the average current to flow through a first mirror transistor in a sense path and a second mirror transistor in a reference path, storing the current mismatch on a capacitor coupled to the gates of the first mirror transistor and the second mirror transistor, disconnecting the memory cell from the reference path and disconnecting the reference source from the sense path, enabling the cell current only to flow through the sense path, and determining the output level of the memory cell.

An apparatus for correcting at least one bit error within a coded bit sequence includes an error syndrome generator and a bit error corrector. The error syndrome generator determines the error syndrome of a coded bit sequence derived by a multiplication of a check matrix with a coded bit sequence.

An apparatus for detecting an error within a coded binary word includes an error corrector and an error detector. The error corrector corrects a correctable bit error within a faulty subset of bits of a faulty coded binary word coded by an error correction code, so that the corrected subset of bits is equal to a corresponding subset of bits of a code word of the error correction code, if the error corrector works faultlessly. Further, the error detector determines an error detection bit sequence indicating whether or not an error detector input binary word is a code word of the error correction code. The error detector input binary word is based on a corrected coded binary word containing the corrected subset of bits and maximally a proper subset of bits of the faulty coded binary word.

A reference current integrator and a sensed current integrator are coupled to form a differential sense amplifier. The differential sense amplifier is coupled to receive a bitline current signal from a flash memory, and the reference current integrator is coupled to receive a current signal from a reference memory cell. Integration continues until a desired voltage or time is reached, resulting in a sufficiently reliable output. The differential current integrating sense amplifier is also used for instrumentation, communication, data storage, sensing, biomedical device, and analog to digital conversion.

A computer implemented method is represented for providing to a user a context menu with entries representing relationships. The relationships are applicable to relate objects selected from a set of objects. The method comprises following method operations: receiving a first identification of a first selected object from the set of objects, receiving a second identification of a second selected object from the set of objects, identifying object types of the selected objects in a plurality of object types, determining one or more relationship types of which one or more relationships are applicable to the selected objects by using the identified object types, and generating for the context menu an entry representing a relationship of the one or more relationship types, wherein the relationship is selectable by the user to be created between the selected objects.

This disclosure relates to a method and system for automatically generating selection conditions associated with component variants represented in a hierarchical node structure in a product configuration system. The selection conditions relate to a determination of when component variants are to be included in a configurable product. The method and system may involve receiving relationship information for component variants at a first node level of the node structure, and determining what combinations may be formed from the component variants based on the relationship information. The method and system may further involve forming assembly variants corresponding to the combinations, at a second node level higher than the first node level, and forming selection conditions corresponding to the assembly variants based on selection conditions corresponding to the component variants.

A system and method of receiving orders, placing orders in an order matrix, determining potential production periods for an order, rescheduling orders, and generating a bill of materials. The method receives an order having one or more tokens out of a set of possible tokens. Each token is a combination of a characteristic and a value of the characteristic. The orders are placed in an order matrix. An order restriction matrix for the orders is generated based on certain selection conditions. The method then examines the restrictions that apply to the order and derives an order derived production restriction matrix for the order, which is evaluated to determine possible production periods for the order. The order matrix may also be used to generate a bill of materials.

A sense amplifier for nonvolatile memories includes a first line path (precharging path) having a first transistor and a third transistor connected in series with the bit line for a memory cell that is to be read. The sense amplifier also includes a second line path (reading path), running parallel to the first line path, in which a transistor diode and a fourth transistor are connected in series with the bit line. The gates of the third transistor and of the fourth transistor are at the same potential, in particular, are connected to one another.
