    • A memory having an array of memory cells. The array includes a plurality of normal memory cells and a redundant memory cell. A decoder is provided for selecting an addressed one of the normal memory cells in response to an address and a normal condition signal and adapted address the redundant memory cell in response to the address and a fault condition signal. A redundant decoder is provided having an electronically erasable read-only-memory cell. The redundant decoder is adapted to produce the normal condition signal and to convert the normal condition signal into the fault condition signal when such read-only-memory cell is programmed into a fault condition. Each one of the read-only memory cells include a flash memory cell, a ferroelectric memory cell, or other such type of electronically erasable read-only memory cell which is substantially non-volatile and is able to retain its programmed state for a relatively long period of time. With such an arrangement, because the electronically erasable read-only-memory cell is electronically programmable, a defective normal memory cell may be replaced with a redundant memory cell the memory is packaged.

    • In a process for drying microporous, fluid-containing particles, the heat required for increasing the temperature is supplied by convection by reducing the interfacial tension of the fluid, preferably to 0 to 1/10, in particular to 0 to 1/20, of the interfacial tension of the fluid at room temperature, by appropriately increasing the temperature at from close to the critical pressure to supercritical pressure of the fluid. Furthermore, microporous, three-dimensionally networked particles are prepared by a process in which the drying process is used. In addition, an apparatus is used for carrying out the drying process, the apparatus comprising a pressure container having an inner container and pressure-withstanding outer container and suitable measuring and control apparatuses and pump apparatuses and heat exchangers, the inner container being provided for holding the particles to be dried and a gap being provided between the inner container and the outer container.
