  • Patent number: 7561485
    Abstract: 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: Grant

  • Patent number: 7505326
    Abstract: 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.

  • Patent number: 7249215
    Abstract: 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.

  • Patent number: 7181565
    Abstract: 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.

  • Patent number: 7176750
    Abstract: 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.

  • Publication number: 20060038609
    Abstract: 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.

  • Patent number: 6816404
    Abstract: 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.
