  • Patent number: 8437204
    Abstract: Some embodiments regard a method comprising: controlling a row of cells of a memory array with a first signal; controlling a column of cells of the memory array with a second signal; transferring data from a cell activated by both the first signal and the second signal to a pair of bit lines associated with the cell; and using the data from the pair of bit lines as read data and as data written back to the cell to ensure the cell stores valid data.
    Type: Grant

  • Patent number: 7577052
    Abstract: A power control circuit for an integrated circuit module includes at least one switch device coupled between a supply voltage and a power node of the integrated circuit module; and a switch control module having a first terminal coupled to the switch device, a second terminal coupled to a control signal, a third terminal coupled to a first storage node of at least one tracking cell, a fourth terminal coupled to a second storage node of the tracking cell, and a fifth terminal coupled to the power node of the integrated circuit module, for controlling the switch device to pass the supply voltage to the power node with or without a substantial voltage drop depending on an operation mode of the integrated circuit module.
