摘要:
A memory (10) is organized as a matrix rows and columns of memory cell circuits (100) and comprises bit line conductors (12) coupled to rows of the memory cells (100). A sensing circuit (14) is coupled to the bit line conductors (12). The sensing circuit (14) is arranged to form respective data signals, each by comparing a respective signal from a plurality of the bit line conductors (12) with a reference level that is common for the bit line conductors (12). A reference level selection circuit (16) with inputs coupled to the plurality of bit line conductors (12) is arranged to control the reference level. The reference level selection circuit (16) selects the reference level dependent on respective analog signal levels on the plurality of the bit line conductors (12), so that analog signal levels from at least respective ones of the plurality of bit line conductors (12) lie on respective sides of the reference level.

An amplifier/buffer composed from circuit elements of a single threshold and single conductivity type, comprising an input stage for receiving one or more inputs for buffering/amplification and providing an intermediate to control output of the amplifier/buffer. The intermediate signal is provided to a boosting circuit configured to boosts said signal when said signal has exceeded a predetermined value. The amplifier/buffer further has an output stage for receiving at least said signal and providing an amplified/buffered output.
摘要:
In a method of manufacturing a semiconductor device comprising a semiconductor body 1 which is provided at a surface 2 with a transistor comprising a gate structure 21, a patterned layer 10 is applied defining the area of the gate structure 21. Subsequently, a dielectric layer 18 is applied in such a way, that the thickness of the dielectric layer 18 next to the patterned layer 10 is substantially equally large or larger than the height of the patterned layer 10, which dielectric layer 18 is removed over part of its thickness until the patterned layer 10 is exposed. Then, the patterned layer 10 is subjected to a material removing treatment, thereby forming a recess 19 in the dielectric layer 18, and a contact window 28,29 is provided in the dielectric layer. A conductive layer 30 is applied filling the recess 19 and the contact window 28,29, which conductive layer 30 is subsequently shaped into the gate structure 21 and a contact structure 26,27 establishing an electrical contact with the surface 2 of the semiconductor body 1.
