    摘要: A memory system includes a plurality of gain memory cells connected via bit bits to sense amplifiers with each sense amplifier having at least two pairs of metal oxide semiconductor (MOS) transistors which have opposite conductivity types. Each gain memory cell has two serially connected n-channel MOS transistors with a diode connected between a gate of a first of the transistors and a source thereof. Three illustrative embodiments of sense amplifiers are used with the gain memory cells.

    摘要: A MOS transistor includes an upper source/drain region, a channel region, and a lower source/drain region that are stacked as layers one above the other and form a projection of a substrate. A gate dielectric adjoins a first lateral area of the projection. A gate electrode adjoins the gate dielectric. A conductive structure adjoins a second lateral area of the projection in the region of the channel region. The conductive structure adjoins the gate electrode.

    摘要: An electrically writable and erasable read-only memory cell arrangement having memory cells. Each of the memory cells having an MOS transistor having a floating gate (6"). The MOS transistors are arranged in rows which run parallel. Adjacent rows run in each case alternately on the bottom of longitudinal trenches (4) and between adjacent longitudinal trenches (4). An area requirement for each memory cell of 2F.sup.2 (F: minimum structure size) is achieved by self-aligning process steps.

    摘要: In the memory cell arrangement, each memory cell consists of a field-effect transistor comprising a gate dielectric (14) which contains at least one ferroelectric layer (142). Depending on the sign of the remanent polarization of the ferroelectric layer (142), the field-effect transistor exhibits one of two different threshold voltages which have the same sign and which are allocated to the logic states "0" and "1". Information is written in by repolarizing the ferroelectric layer (142), information items are read by applying a voltage to the gate electrode of the field-effect transistor, the voltage being between the two threshold voltages.
