Title: Magnetic non-volatile memory element
Inventor: KOBAYASHI KAORU
IPC: H01L21/76
Filed: 2003-07-02
Abstract: A magnetic non-volatile memory element having a sufficient magnetic shield effect against an external magnetic field. A first and a second magnetic shield layer (60a, 60b) are formed by using soft magnetic metal on the lower surface of a transistor section (20) of the mounting side of an MRAM element (10) and on the upper surface of the bit line (50) of the side opposite to the element mounting side, respectively. A passivation film (70) is formed on the second magnetic shield layer (60b). Thus, a magnetic flux coming from an external magnetic field is suppressed to or below the inverting magnetic field intensity of the MRAM element (10), thereby improving reliability. Furthermore, by using soft magnetic metal for the shield layers (60a, 60b), formation is enabled by using the sputter method. If this soft magnetic metal is partially common to the target element forming the layers of the MRAM element, it is possible to effectively form the magnetic shield layers (60a, 60b) by using the same sputter device used for the layers of the MRAM element (10).

Title: Method and device for building a variable-length error-correcting code
Inventor: LAMY CATHERINE
IPC: H03M7/40
Filed: 2004-03-16
Abstract: The invention relates to a variable- length error-correcting (VLEC) code construction method, in which the main steps are : defining all the needed parameters, generating a code having a fixed length L1, storing in a set W thus obtained all the possible L1-tuples distant of the minimum diverging distance d ' min! from the codewords (one extra-bit being affixed at the end of all words if the new set W thus obtained is not empty), deleting all words of W that do not satisfy a distance criterion with all codewords, and verifying that all words of the final set W satisfy another distance criterion. Assuming that all distributions of number of codewords for the best VLEC codes have a similar curve allure of a bell shape type, it is then proposed, according to the invention, to define an optimal length value Lm until which the number of codewords increases with their length, whereas it decreases after said value Lm. According to this new construction method, called Lm optimization, it is possible to apply the so-called "Ls optimization" method with avoiding the edges of the curve and to work locally, wherein Ls represents a length to which the thod skips back in the codeword deletion stage.
