  • Patent number: 7042776
    Abstract: A method and circuit for adjusting the read margin of a self-timed memory array. The electronic circuit, including: a memory cell array including a sense amplifier self-timed decode circuit adapted to set a base read time delay of the memory cell array; and a read delay adjustment circuit coupled to the memory cell array, the read delay adjustment circuit adapted to adjust the base read time delay of the memory array based on an operating frequency of the memory cell array.

  • Patent number: 6181641
    Abstract: A memory device includes a plurality of memory cells arranged in rows and columns. The memory cells are divided into a plurality of sub-arrays. The memory cell further includes a plurality of word lines connecting rows of the memory cells, and a plurality of bit line pairs connecting columns of the memory cells. An address transition detect (ATD) circuit detects an address transition for a selected memory cell and generates an ATD pulse in response thereto. A respective bit line precharge circuit is associated with each of the plurality of sub-arrays. An ATD pulse distribution circuit distributes the ATD pulse to only a selected sub-array containing the selected memory cell to activate only the bit line precharge circuit of the selected sub-array and not activate precharge circuits of other non-selected sub-arrays.
