Patents by Inventor Sayeed A. Badrudduza

Sayeed A. Badrudduza has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8913456
    Abstract: A memory including an array of memory cells, word lines, and voltage supply lines. Each voltage supply line of the plurality of voltage supply lines is coupled to a first voltage supply terminal of a subset of memory cells of subsets of memory cells of the array. Each memory cell of the array is coupled to a word line. The memory includes a row decoder that controls a voltage on each of the word lines and controls a voltage on each of the voltage supply lines. The row decoder provides a low voltage state voltage on one of the voltage supply lines during a write operation to a subset of memory cells coupled to the voltage supply line and the row decoder provides a high voltage state voltage to the voltage supply line during a read operation of the subset of the memory cells.

  • Patent number: 8773940
    Abstract: A memory cell including a cross-coupled latch with corresponding storage nodes, and further including first and second write pass gate transistors and first and second read pass gate transistors. The write pass gate transistors are controlled by a write word line and the read pass transistors are controlled by a read word line. Each read and write pass gate transistor is coupled between a storage node and either a bit line or a complementary bit line. The write pass gate transistors are implemented at a first strength level and the read pass gate transistors are implemented at a second strength level which is less than the first strength level. In this manner, the read and write margins are independently configurable without negatively impacting each other.

  • Patent number: 8638592
    Abstract: An SRAM has at least two sets of pass transistors for coupling at least two sets of bit lines to true and complement data nodes of an SRAM cell based on the assertion of at least two word lines. The cell includes two pull up transistors and two pull down transistors coupled to the true and complement data nodes. None of the pass transistors are implemented in an active area that includes a pull up transistor or a pull down transistor of the cell.
