摘要:
Embodiments of the present invention provide a magnetic memory. In one embodiment, the magnetic memory comprises an array of memory cells configured to provide resistive states, and a read circuit. The read circuit is configured to sense a resistance through a memory cell in the array of memory cells to obtain a sense result and categorize the sense result into one of at least three different categories comprising a middle category situated between the resistive states.

A system for error correction coding and decoding information is disclosed. In one embodiment, the first and second encoders are each configured to encode the information, wherein the second encoder has a higher capability than the first encoder. First and second decoders are configured to recover the information, wherein the second decoder recovers the information encoded by the second encoder only if the first decoder cannot recover the information.

Embodiments of the present invention provide a data storage and retrieval system operating on a host computer. The data storage and retrieval system comprises a sparing system configured to replace defective memory sections of a memory device with replacement memory sections of the memory device, and an error correction code system. The error correction code system is configured to encode data with an error correction code to store the data into the memory device and decode the encoded data with the error correction code to retrieve the data from the memory device.
摘要:
The invention relates to systems and methods for covering portions of one or more block members after laying of the block members to allow filling of hollow cores in the block members with filler materials. A cover member prevents the filler materials from entering into channels or apertures covered by the cover member. A cover member has a top section and a downwardly depending member extending from the top section. The downwardly depending member extends into a portion of the block, and may engage with the block member to retain the cover member in position.
摘要:
The invention provides novel railroad ties manufactured from novel composite materials that possess excellent physical and performance characteristics matching or exceeding existing concrete RRTs. The RRTs of the invention can be readily produced from widely available, low cost raw materials by a process suitable for large-scale production with improved energy consumption and more desirable carbon footprint and minimal environmental impact.
摘要:
Provided are derivatives substituted by urea associated with 4-substituted-(3-substituted-1H-pyrazole-5-amino)-pyrimidine-2-amino of formula (I), wherein these compounds may selectively regulate or inhibit an information transmission process controlled by natural or variant tyrosine kinase. Also provided are preparation methods and uses of the compounds.
摘要:
Apparatus for gas delivery (10), particularly at low pressure and volume. The apparatus has a gas reservoir, a delivery line between the gas reservoir (14) and a gas outlet (68) and a first supply line between a first inlet connect able to a first gas supply and the gas reservoir. A pressure control line is provided with an inlet connect able to a second gas supply. The pressure control line is coupled to the gas reservoir to thereby control the pressure in the gas reservoir.
