Publication number: 20080270681Abstract: A main memory (10) comprises a plurality of physical blocks of memory locations. The main memory (10) supports erasing of at least a physical block at a time. Pointer information is stored in a subset (40, 42) of the blocks for use to identify respective ones of the physical blocks that are assigned to respective functions. Successive versions of the pointing information are stored at mutually different memory locations initially in a first block (40) in the subset (40, 42). A subsequent version of the pointing information that is more recent than the successive versions is stored in a second block (42) of the subset (40, 42) at least after the first block (40) has been filled. The first block (40) is erased after storing the subsequent version. On start up of the main memory the pointing information is recovered by testing which of the blocks of the subset (40, 42) contains a most recent version of the pointing information.Type: ApplicationFiled: December 13, 2006Publication date: October 30, 2008Applicant: NXP B.V.Inventors: Victor M.G.

Patent number: 7224634Abstract: The present invention provides a special structure of magnetic elements, e.g. MRAM elements, as a security device for IC's containing magnetic memory cells. In an example embodiment, the structure may comprise a combination of two or more associated magnetic elements with pre-set anti-parallel magnetization directions. By determining the polarisation directions of the magnetic elements, exposure to an external magnetic field can be detected. Inverse polarisation directions indicate a normal situation, aligned polarisation directions indicate that the MRAM-array has been exposed to an external field. In this way it can be detected whether a user has tried to erase or alter the data stored in the MRAM in an illegal way. The IC can regularly check the resistance of the security system during operation. Upon detection of a field exposure, the IC can erase all MRAM data, reset itself or, block its functioning.Type: GrantFiled: December 15, 2003Date of Patent: May 29, 2007Assignee: NXP B.V.Inventors: Kars-Michiel Hubert Lenssen, Adrianus Johannes Maria Denissen, Nicolaas Lambert

Patent number: 7124337Abstract: Real-time audio video applications require guaranteed request service times from a hard disc drive. This requirement is not always fulfilled due to some unexpected delays in service times. Re-allocated sectors are one of the causes of such delays. A scheme for conversion of re-maps into slips in a hard disc drive is suggested. Converting re-allocated sectors into slipped or skipped sectors can prevent such a delay, since slipped sectors cause much less or even negligible performance loss than re-allocated sectors.Type: GrantFiled: December 23, 2002Date of Patent: October 17, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Nicolaas Lambert, Ozcan Mesut, Rudi Jozef Marie Wijnands

Patent number: 7096327Abstract: A system (100, 300) like a video on demand server has a storage medium (106) with a number of files (200) from which data can be fetched or in which data can be stored. A file contains a number of clusters (202, 204, 206) and each cluster contains a number of storage sectors (208) that are physically successively organized on the storage medium. When a new stream is requested, either for reading or writing, a block size (210) is determined for the new stream. The block size is large enough to support the rate of the stream and is chosen such that a cluster can be read with an integer number of blocks by evenly partitioning the size of the cluster into the size of the blocks reading the cluster.Type: GrantFiled: February 16, 2001Date of Patent: August 22, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Johannes Henricus Maria Korst, Nicolaas Lambert, Ronald Marcel Tol, Adrianus Johannes Maria Denissen, Marcel Lambertus Leonardus Bijsterveld, Hong Li, Robert Jochemsen
