| 20100277219 | Clock Gater with Test Features and Low Setup Time - A clock gater circuit comprises a plurality of transistors having source-drain connections forming a stack between a first node and a supply node. A given logical state on the first node causes a corresponding logical state on an output clock of the clock gater circuit. In one embodiment, a first transistor of the plurality of transistors has a gate coupled to receive an enable input signal. A second transistor is connected in parallel with the first transistor, and has a gate controlled responsive to a test input signal to ensure that the output clock is generated even if the enable input signal is not in an enabled state. In another embodiment, the plurality of transistors comprises a first transistor having a gate controlled responsive to a clock input of the clock gater circuit and a second transistor having a gate controlled responsive to an output of a delay circuit. The delay circuit comprises at least one inverter, wherein an input of the delay circuit is the clock input, and wherein a first inverter of the delay circuit is coupled to receive a test input signal and is configured to force a first logical state on an output of the first inverter responsive to an assertion of the test input signal. | 11-04-2010 |
| 20100308790 | APPARATUS AND METHOD FOR TESTING DRIVER WRITEABILITY STRENGTH ON AN INTEGRATED CIRCUIT - An apparatus and method for testing driver write-ability strength on an integrated circuit includes one or more drive detection units each including a number of drivers. At least some of the drivers may have a different drive strength and each may drive a voltage onto a respective driver output line.

Each level shifter circuit may be coupled to a first and a second voltage supply. Each level shifter circuit may also receive an input signal that is referenced to the first voltage supply, and to generate an output signal that is referenced to the second voltage supply. In addition, each level shifter module may include detection logic that may detect an output value of each of the level shifter circuits. The control circuit may be configured to iteratively change the voltage output from one of the voltage supplies, and maintaining a voltage on the other voltage supply while the input signal is provided to the level shifter circuits. The detection logic may capture the output value upon each change in voltage. | 12-09-2010 |

The integrated circuit may also include a selection circuit configured to select a particular SRAM cell in response to a selection input. An oscillator circuit such as a ring oscillator, for example, on the integrated circuit may be configured to oscillate at a frequency that is dependent upon a read current of a selected SRAM cell during operation in a first mode. A frequency determining circuit that is coupled to the oscillator circuit may be configured to output a value corresponding to the frequency of oscillation of the oscillator circuit. | 12-23-2010 |
| 20110012643 | APPARATUS AND METHOD FOR TESTING SENSE AMPLIFIER THRESHOLDS ON AN INTEGRATED CIRCUIT - An apparatus and method for testing sense amplifier threshold voltages on an integrated circuit includes one or more sense amplifier modules each including a number of sense amplifier circuits, a voltage generator unit, and detection logic. The voltage generator unit may select a differential voltage to supply to at least some of the sense amplifier circuits, and each sense amplifier circuit may be configured to generate an output value that is dependent upon the applied differential voltage in response to receiving an enable signal. The detection logic may detect and capture an output value of each of the sense amplifier circuits. In one implementation, the voltage generator unit may iteratively select a different differential voltage in response to a control input. Accordingly, the detection logic may capture the output value of the sense amplifiers after each change in differential voltage. | 01-20-2011 |
| 20110202809 | Pulse Flop with Enhanced Scan Implementation - In an embodiment, a clocked storage device such as a pulse flop is provided. The pulse flop includes a latch coupled to receive a scan data input to the pulse flop. The latch receives the scan data input during one of the phases of the clock, and retains the received input during the other phase. The other phase is the phase in which the pulse to the pulse flop occurs. Thus, when scan data is captured in the pulse flop, the latch at the next pulse flop in the chain may be closed and may prevent a race condition in propagating the scan data. | 08-18-2011 |
