Patent number: 7561485Abstract: A memory system is disclosed. In one embodiment, the memory system includes a first bitline, where the first bitline produces a first transient current. The memory system also includes a sense amplifier coupled to the first bitline. The memory system also includes a second bitline coupled to the sense amplifier, where the second bitline produces a second transient current that is equal to the first transient current. The sense amplifier enables the first and second transient currents to be canceled. According to the system disclosed herein, the state of a memory cell may be determined without being adversely affected by transient currents.Type: GrantFiled: January 12, 2007Date of Patent: July 14, 2009Assignee: Atmel CorporationInventors: Gabriele Pelli, Lorenzo Bedarida, Simone Bartoli, Giorgio Bosisio

Patent number: 7505326Abstract: A signal generator circuit is configured to generate program signals for a memory array. The program signals are applied to word lines in the memory array, and have a transient state based on a coupling characteristic of the word lines and selector gates. The transient state is configured to minimize coupling between the word lines and the gates of the selectors so that a state of each selector remains unchanged during the transient state.Type: GrantFiled: October 31, 2006Date of Patent: March 17, 2009Assignee: ATMEL CorporationInventors: Stefano Sivero, Mirella Marsella, Mauro Chinosi, Giorgio Bosisio

Patent number: 7249215Abstract: System for configuring parameters used in flash memory devices. A load instruction and associated address are retrieved from a memory, and the address is used to select a configuration register storing a configuration value. The configuration value is loaded to an associated dedicated register to configure a parameter of the flash memory in a flash memory operation.Type: GrantFiled: December 7, 2006Date of Patent: July 24, 2007Assignee: Atmel CorporationInventors: Stefano Surico, Simone Bartoli, Mirella Marsella, Giorgio Bosisio

Patent number: 7181565Abstract: Method and system for configuring parameters used in flash memory devices. A load instruction and associated address are retrieved from a read-only memory, and the address is used to select a configuration register storing a configuration value. The configuration value is loaded to an associated dedicated register to configure a parameter of the flash memory in a flash memory operation. In another aspect, one or more selected configuration values not stored in a ROM are changed if a tested flash memory operation is not within desired specifications.Type: GrantFiled: November 10, 2005Date of Patent: February 20, 2007Assignee: Atmel CorporationInventors: Stefano Surico, Simone Bartoli, Mirella Marsella, Giorgio Bosisio

Patent number: 7176750Abstract: A fast power-on band-gap reference circuit includes a buffer, a first band-gap logic, and a second high drive band-gap logic. During power-on of the band-gap reference circuit, both the first band-gap logic and the second high drive band-gap logic are activated, in which the first band-gap logic charges an output of the first band-gap logic and the second high drive band-gap logic charges a capacitance associated with an output of the band-gap reference circuit. When the output of the first band-gap logic reaches a predetermined value, the second high drive band-gap logic is deactivated and the output of the first band-gap logic is couple to the output of the band-gap reference circuit through the buffer.Type: GrantFiled: May 9, 2005Date of Patent: February 13, 2007Assignee: Atmel CorporationInventors: Giorgio Oddone, Stefano Sivero, Giorgio Bosisio, Andrea Bettini

Publication number: 20060038609Abstract: A fast power-on band-gap reference circuit includes a band-gap logic and a band-gap dummy logic. During power-on, both the band-gap logic and the band-gap dummy logic are activated and charges the capacitance of a band-gap line. When an output of the band-gap logic reaches a predetermined value, the band-gap dummy logic is deactivated. Thus, the band-gap dummy logic, with a high drive capability, charges the band-gap capacitance at the same time the band-gap logic starts to generate the compensate temperature voltage. In this manner, the band-gap reference circuit reaches its stable, functional state faster than conventional circuits, in the range of a few microseconds.Type: ApplicationFiled: May 9, 2005Publication date: February 23, 2006Inventors: Giorgio Oddone, Stefano Sivero, Giorgio Bosisio, Andrea Bettini

Patent number: 6816404Abstract: The phase-change nonvolatile memory array is formed by a plurality of memory cells extending in a first and in a second direction orthogonal to each other. A plurality of column-selection lines extend parallel to the first direction. A plurality of word-selection lines extend parallel to the second direction. Each memory cell includes a PCM storage element and a selection transistor. A first terminal of the selection transistor is connected to a first terminal of the PCM storage element, and the control terminal of the selection transistor is connected to a respective word-selection line. A second terminal of the PCM storage element is connected to a respective column-selection line, and a second terminal of the selection transistor is connected to a reference-potential region while reading and programming the memory cells.Type: GrantFiled: December 12, 2002Date of Patent: November 9, 2004Assignees: STMicroelectronics S.r.l., OVONYX, Inc.Inventors: Osama Khouri, Ferdinando Bedeschi, Giorgio Bosisio, Fabio Pellizzer
