Patent number: 7923813Abstract: A One Time Programmable (OTP) memory cell (10) comprising a first, metallic layer (12) coated with a second, conductive stable transition compound (14) with an insulating layer (16) there-between. The first and second layers (12, 14) are selected according to the difference in Gibbs Free Energy between them, which dictates the chemical energy that will be generated as a result of an exothermic chemical reaction between the two materials. The materials of the first and second layers (12, 14) are highly thermally stable in themselves but, when a voltage is applied to the cell (10), a localized breakdown of the insulative layer (16) results which creates a hotspot (18) that sets off an exothermic chemical reaction between the first and second layers (12, 14). The exothermic reaction generates sufficient heat (20) to create a short circuit across the cell and therefore reduce the resistance thereof.Type: GrantFiled: May 4, 2006Date of Patent: April 12, 2011Assignee: NXP B.V.Inventors: Paul Van Der Sluis, Andrei Mijiritskii, Pierre H. Woerlee, Victor M. G Van Acht, Nicolaas Lambert

Publication number: 20080285416Abstract: A record carrier comprises three layers that react with each other when irradiated to form a mark on the record carrier. The three layers are separated by a two separating layers that prevent direct contact of the three layers thus providing stability to the record carrier. By irradiating one or both separating layers a region of those separating layers is destroyed or altered whereby an opening is created and the reaction of the layers adjacent to the separating layer is no longer prevented in that region and a mark can be formed. Since either one or two reactions can take place if one or both separating layers are destroyed or altered multiple reflection levels for a mark can be obtained, thus enabling multilevel recording where a single mark can represent more information compared to the situation where only two reflection levels can be obtained. The size of the resulting opening determines the size of the mark and can thus be used to create a very small mark allowing high density recordings.Type: ApplicationFiled: June 23, 2005Publication date: November 20, 2008Applicant: Koninklijke Philips Electronics, N.V.Inventors: Erwin Rinaldo Meinders, Andrei Mijiritskii
