    摘要: A memory array includes first, second, third and forth memory cell strings. Each of the first, second, third, and fourth memory cell strings includes a number of serially-coupled memory cells, including a first memory cell and a last memory cell. A first interconnect is coupled to a first bit line and to each of the first, second, third and fourth memory cell strings. The first interconnect includes first, second, third and fourth string input select gates. Each input select gate has a first terminal coupled to the first bit line, and a second terminal coupled to one of the respective first, second, third or fourth memory cell strings.

    摘要: Memory cell transistors with back-channel isolation are produced without using an SOI substrate. With the word line stack acting as a mask, the semiconductor material is etched on both sides of the world line, first anisotropically and then isotropically to widen the etch hole and form an undercut beneath the gate electrode and at a distance from the ONO storage layer forming the gate dielectric. The undercut is filled, whereby a buried oxide layer of at least 20 nm maximum thickness is formed underneath the channel region. The latter is p-doped at a density of at least 1017 cm−3.

    摘要: A memory layer intended for trapping charge carriers over a source region and a drain region is interrupted over the channel so that a diffusion of the charge carriers, which are trapped over the source region and over the drain region, is prevented. The memory layer is limited to regions over the parts of the source region and of the drain region facing the channel and is embedded all around in oxide.

    摘要: For the operation of a memory cell arrangement with MOS transistors as memory cells that comprise a dielectric triple layer (5) with a first silicon oxide layer (51), a silicon nitride layer (52) and a second silicon oxide layer (53) as gate dielectric, whereby the silicon oxide layers are respectively at least 3 nm thick, a first cutoff voltage value is allocated to a first logical value and a second cutoff voltage value of the MOS transistor is allocated to a second logical value for storing digital data. The information stored in the memory cell can be modified by applying corresponding voltage levels, although a complete removal of charge stored in the silicon nitride layer is not possible because of the thickness of the silicon oxide layers. What is exploited when modifying the cutoff voltage is that the electrical field in the dielectric triple layer is distorted by charge stored in the silicon nitride layer.
