    摘要: FLASH memory device contains at least one memory stack. The stack of transistors includes a first (or source) selector transistor, a second (or drain) selector transistor, and a plurality memory cell transistors connected in series therebetween. During an erase operation, each of the first and second selector transistors has a bias applied that releases the select transistors from an electrically floating state together with biasing each of the memory cell transistors.

    摘要: A method is provided for transferring data in a memory that includes memory cells forming memory pages, and a page buffer that includes a register, with signal lines selectively transferring data stored in the register to the memory cells of a selected one of the memory pages and an output interface of the memory. Data read from or to be written to the memory cells of the selected one of the memory pages is at least temporarily stored in the register, and outputs of the register are buffered so as to decouple the outputs of the register from the signal lines. The signal lines include bitlines that are each coupled to some of the memory cells and data lines that are coupled to the output interface of the memory. The buffering comprises selectively driving the bitlines or the data lines according to a data word that is stored in the register.

    摘要: A phase change memory has an array formed by a plurality of cells, each including a memory element of calcogenic material and a selection element connected in series to the memory element; a plurality of address lines connected to the cells; a write stage and a reading stage connected to the array. The write stage is formed by current generators, which supply preset currents to the selected cells so as to modify the resistance of the memory element. Reading takes place in voltage, by appropriately biasing the selected cell and comparing the current flowing therein with a reference value.

    摘要: A circuit for converting a direct current input voltage into an output voltage greater than the input voltage. The circuit includes a charge pump and a block for generating pulse signals of a predetermined frequency to be applied to a control input of the charge pump. The settling time, i.e. the time necessary for the output voltage to attain its operating value and to maintain it with a given precision, is reduced by providing the circuit with charge injection control via modulation of the duty cycle of the pulse signals as a function of the difference between the output voltage, or a predetermined fraction thereof, and a predetermined reference voltage and in such a manner as to reduce the settling time as the difference diminishes. The circuit includes a regulator that controls the charge pump based upon the predetermined reference voltage.
