  • Publication number: 20110050284
    Abstract: A sense amplifier circuit is provided with a first transistor arrangement comprising a first n-type field effect transistor (NFET) having a respective body node, and a second transistor arrangement comprising a second NFET having a respective body node. The second transistor arrangement is electrically coupled to the first transistor arrangement, and the body node of the first NFET is electrically coupled to the body node of the second NFET. The sense amplifier circuit also includes or cooperates with a voltage condition selector that is electrically coupled to the body node of the first NFET and to the body node of the second NFET. The voltage condition selector is configured to assert one of a plurality of voltage conditions at the body node of the first NFET and at the body node of the second NFET.

  • Publication number: 20100260001
    Abstract: A device includes a memory configured so that, in the event that one pass-gate transistor associated with a bit cell is determined to be excessively weak such that reading the bit cell could be undesirably difficult, a second pass-gate transistor can be configured to support a read operation. For example, during a manufacturing test procedure, the access speed of each bit cell at a memory device is determined. If a bit cell fails to achieve a desired access speed, the column of the memory that includes the defective bit cell can be configured to access information stored at the bit cell using the second bit line associated with the second pass-gate transistor.

  • Publication number: 20100157695
    Abstract: A memory device is disclosed that includes a plurality of word-lines, with each word-line connected to at least one bitcell. Each of the plurality of word-lines is connected to a corresponding driver module to drive the word-line in response to a corresponding select signal. Further, each driver module is connected to a level shifter to shift the corresponding select signal so that the driver module provides a level-shifted signal at the first word-line in response to assertion of the first select signal. A single level shifter can be connected to multiple driver modules, thereby reducing the area required to implement level-shifting for multiple word-lines.

  • Publication number: 20090248383
    Abstract: A method of simulating operation of a bitcell includes determining sensitivities of a bitcell model to different component characteristics and device parameters, such as device temperature, operating voltage, and process characteristics. The determined sensitivities are normalized, so that each normalized value represents the relative sensitivity of the bitcell, under the simulated device parameters, to the component characteristic associated with the value. The normalized sensitivity values can be scaled based on a tolerance factor, and the adjusted sensitivities used to model the behavior of each component of the bitcell in subsequent simulations.
