  • Patent number: 7940580
    Abstract: A memory device is disclosed that includes a plurality of word-lines, with each word-line connected to at least one bitcell. Each of the plurality of word-lines is connected to a corresponding driver module to drive the word-line in response to a corresponding select signal. Further, each driver module is connected to a level shifter to shift the corresponding select signal so that the driver module provides a level-shifted signal at the first word-line in response to assertion of the first select signal. A single level shifter can be connected to multiple driver modules, thereby reducing the area required to implement level-shifting for multiple word-lines.
    Type: Grant

  • Patent number: 7379356
    Abstract: A memory includes at least one memory segment that includes an array of memory cells arranged in a plurality of columns, each of the plurality of columns having a corresponding bitline pair. An address decoder includes a row decoder and a column decoder that addresses a selected one of the array of memory cells in a selected one of the plurality of columns in response to a memory address. A sense amplifier generates a data output by sensing a differential voltage from the corresponding bitline pair of the selected one of the plurality of columns in response to a sense amp enable signal. A sense amp enable signal generator generates the sense amp enable signal with adjustable timing, based on sense amp feedback signals.
