Patents by Inventor Philippe Calzi

Philippe Calzi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electronically configurable connection device
    Patent number: 5727169
    Abstract: The use of electromechanical devices for the configuration of the address for access to a peripheral unit in a data-processing system is avoided by replacing them with a non-volatile EEPROM-type memory. The data in non-volatile memory is read as soon as the peripheral unit is put into operation, and the information that it delivers is stored in volatile memory and used as a comparison address to validate the operation of the peripheral unit.
    Type: Grant
    Filed: December 27, 1993
    Date of Patent: March 10, 1998
    Assignee: SGS-Thomson Microelectronics, S.A.

  • CMOS amplifier for memories
    Patent number: 4897569
    Abstract: A read amplifier for memories, using C-MOS technology, consists of a differential stage comprising an balancing circuit used, during the balancing phase, by means of a pre-charging signal and means to memorize the state of the differential stage output during the balancing phase. The invention can be applied especially to RAMs.

  • Integrated circuit provided with switching elements for changeover to redundancy elements in a memory
    Patent number: 4860256
    Abstract: In an integrated circuit provided with a memory including redundancy elements and fuses for switching-over to the redundancy elements, a supplementary terminal for receiving a high voltage is connected to all the fuses and to a circuit which generates low voltage at the time of programming of the memory and which is capable of presenting high impedance when the high voltage is applied, with the result that the entire current flows through the fuses selected for blowout.
