  • Patent number: 6456540
    Abstract: A method and apparatus for a memory device is described. In one embodiment, global Y (GY) enable is gated by the trailing edge of a address transition detection (ATD) pulse. The ATD pulse ensures that the GY enable is off during periods when the memory device is not attempting to read a memory cell. The sense (SEN) node between the GY transistor and drain bias circuit may be charged up and global bit line (GBL) may be grounded. During this time, the power supply current is cut off by the GY transistor itself, thereby eliminating the need of separate cut-off transistors within the drain bias circuit. This permits minimal time delay in sensing after the incoming address is stable.

  • Patent number: 6442069
    Abstract: A flash memory using a pre-sensing amplifier coupled to receive differential inputs from a pair of memory cells of said flash memory array and to generate a differential output from the pre-sensing amplifier. The differential output is coupled to a bus, which is also coupled to a post-sensing amplifier. The differential configuration on the bus allows marginal voltage differences to be detected by the post-sensing amplifier so that logic states from the flash memory can be sensed without the bus transitioning to half of the supply voltage.
