(Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service
ALEXANDRIA, Va., Feb. 1 -- Unity Semiconductor, Sunnyvale, Calif., has been assigned a patent (8,363,443) developed by Christophe J. Chevallier, Palo Alto, Calif., Seow Fong Lim, Fremont, Calif., and Chang Hua Siau, Saratoga, Calif., for "circuits and techniques to compensate data signals for variations of parameters affecting memory cells in cross-point arrays."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "Embodiments of the invention relate generally to semiconductors and memory technology, and more particularly, to systems, integrated circuits, and methods to implement circuits configured to compensate for parameter variations that affect the operation of memory elements, such as memory elements based on third dimensional memory technology. In at least some embodiments, an integrated circuit includes a cross-point array comprising memory elements disposed among word lines and bit lines, where a parameter can affect the operating characteristics of a memory element. The integrated circuit further includes a data signal adjuster configured to modify the operating characteristic to compensate for a deviation from a target value for the operating characteristic based on the parameter. In some embodiments, the memory element, such as a resistive memory element, is configured to generate a data signal having a magnitude substantially at the target value independent of variation in the parameter."
The patent application was filed on Jan. 31, 2011 (12/931,422). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,363,443&OS=8,363,443&RS=8,363,443
