    Abstract: The use of charge pumps to supply bit lines, when programming memory cells connected to a bit line, is avoided by pre-charging this bit line simultaneously with the neutralization of the selection of this bit line. Subsequently, the pre-charging potential is uncoupled and the effects of the neutralization are stopped. It is known that this method of action prevents the breakdown of a single programming potential generator, used to supply all the bit lines. This results in a gain in space in the lay-out of the control circuits of the memory cells in the memory plane. This method can be implemented especially in page mode programming for memories where the memory cells have EEPROM-type floating-gate transistors.

    Abstract: The present invention pertains to a dynamic memory. The voltage of the hot spot of the storage capacitor is carried to a value such that all the cells comprise the same logic value, owing to a potential generator. It is thus possible to write and read bit fields on a large-capacity memory at high speed. This device has applications with respect to image memories and for manufacturing tests.

    Abstract: The present invention provides a process for producing alveolar cellulosic products (sponges, sponge-cloths, etc.) from a cellulosic raw material, the process comprising:at least partially dissolving a cellulosic raw material in an intrinsic solvent for cellulose;incorporating an effective quantity of at least one pore-forming agent into the resulting mixture, with mixing; said pore-forming agent(s), being compatible with the cellulosic mixture, being capable of generating macro- and micro-pores when it/they is/are actuated;gelling the homogeneous dough thus obtained;treating said gelled dough under conditions in which the cellulose precipitates out and the pore-forming agent(s) present are actuated.The process is an advantageous alternative to the viscose process which is a polluting process. The properties of the products obtained are completely similar to those of products obtained using the viscose process. The (novel) products form part of the invention.
