  • Patent number: 9704580
    Abstract: A non-volatile memory device using existing row decoding circuitry to selectively provide a global erase voltage to at least one selected memory block in order to facilitate erasing of all the non-volatile memory cells of the at least one selected memory block. More specifically, the erase voltage is coupled to the cell body or substrate of memory cells of the at least one selected memory block, where the cell body is electrically isolated from the cell body of non-volatile memory cells in at least one other memory block. By integrating the erase voltage path with the existing row decoding circuitry used to drive row signals for a selected memory block, no additional decoding logic or circuitry is required for providing the erase voltage to the at least one selected memory block.

  • Patent number: 9384838
    Abstract: A non-volatile memory device having a memory array organized into a plurality of memory blocks, having either planar memory cells or stacks of cells. Row decoding circuitry of the memory device is configured to select a group of the plurality of memory blocks in response to a first row address, and to select a memory block of the group for receiving row signals in response to a second row address. Row decoding circuitry associated with each group of memory blocks can have a row pitch spacing that is greater than a row pitch spacing of a single memory block and less than or equal to a total row pitch spacing corresponding to the group of memory blocks.
