Abstract: PROBLEM TO BE SOLVED: To provide a method for testing many word lines of a semiconductor memory assembly in a multiple WL wafer test in which a multiple wafer test can be performed quickly without needing much cost. SOLUTION: When an active word line(WL) is in a power-down state, a non-active word line is separated from negative VNWL voltage and made highly resistant immediately before the power-down of the active word line to prevent the rise of the non-active word line having negative voltage.

Abstract: Production of a heat deviating surface of a component (1) comprises inserting trenches (3) into the component using an etching process. Preferred Features: The surface of the component is covered with a masking layer (2) in prescribed regions and during etching trenches are etched into the non-covered regions of the surface of the component. An etching solution comprising a 25 vol.% tetramethylammonium hydroxide solution or ethylene diamine or hydrazine is used at 70 deg C. The masking layer is applied to regions of the surface of the component in which the component is divided during the subsequent process steps.

Abstract: The circuit generates a control voltage derived from a reference current per differential amplifier acting as a receiver to set the correct operating point. Switching elements for each receiver in a line carrying a current for generating the control voltage are permanently closed in working mode by a trigger signal (EN) to continuously deliver the current and are closed periodically or at discrete times in standby mode by a refresh signal. The circuit generates a control voltage derived from a reference current (IREF) for each differential amplifier (6,7) functioning as a receiver to set the correct operating point. It has switching elements (10-12) for each receiver in a line (13) carrying a current for generating the control voltage and that are permanently closed in working mode by a trigger signal (EN) to continuously deliver the current and that are closed periodically or at discrete times in standby mode by a refresh signal (SRF). Independent claims are also included for the following: a DRAM memory.

Abstract: The method involves closing a control unit (MUX) to connect a sense amplifier (SAM) with a bit line (BL), and activating a word line (WL) to activate a memory cell (M) for selection. The sense amplifier is activated to evaluate information of the bit line, and the control unit is opened to disconnect the bit line by the sense amplifier. The selected information is delivered on a data bus (DAT). An independent claim is also included for a dynamic circuit memory with a selection circuit.
