    Abstract: Rather than merely carrying out a BIST test by verifying whether a memory cell accurately stores a “1” or “0” under normal read/write conditions, aspects of the present discloser relate to BIST tests that test the read and/or write margins of a cell. During this BIST testing, the read and/or write margins can be incrementally stressed until a failure point is determined for the cell. In this way, “weak” memory cells in an array can be identified and appropriate action can be taken, if necessary, to deal with these weak cells.

    Abstract: Some embodiments of the present disclosure relate to improved reliability verification techniques for semiconductor memories. Rather than merely carrying out a BIST test by verifying whether a memory cell accurately stores a “1” or “0” under normal read/write conditions, aspects of the present invention relate to BIST tests that test the read and/or write margins of a cell. During this BIST testing, the read and/or write margins can be incrementally stressed until a failure point is determined for the cell. In this way, “weak” memory cells in an array can be identified and appropriate action can be taken, if necessary, to deal with these weak cells.

    Abstract: The control voltage for a VCO (voltage controlled oscillator) is produced in a phase locked loop which in turn is controlled by a computer (40) including an integrated analog circuit (42). First the oscillator control voltage is set to a predetermined value. Then, voltage varying steps are performed. For performing these steps, the circuit includes a main frequency divider and a reference frequency divider both functioning as counters. The beginnings of the counting of each divider are synchronized with each other. The oscillator control voltage is increased by a predetermined voltage difference or increment when the reference divider completes its counting period prior to the main divider completing its counting. The oscillator control voltage is decreased by a predetermined voltage difference or decrement when the main divider finishes its counting period prior to the reference divider finishing its count.

    Abstract: A fuel injection valve for internal combustion engines, having a fuel inlet conduit, which originates at a connection stub and discharges at at least one injection opening. A rodlike fuel filter is inserted into the fuel inlet conduit and is guided in the inlet conduit on opposite axial ends. Two groups of longitudinal grooves are formed in the jacket face each of which are axially closed on one end. The first group of longitudinal groove originate at an upper end face of the fuel filter remote from the injection opening, and the second group originates at a lower fuel filter end face oriented toward the injection opening. The size of the flow cross section at the fuel filter and the size of the flow cross section of the inlet conduit in the region downstream of the fuel filter amounts to from approximately 5-10 times the size of the total flow cross section of all the injection openings in the fuel injection valve.
