| 20100246311 | CLOCK GENERATORS, MEMORY CIRCUITS, SYSTEMS, AND METHODS FOR PROVIDING AN INTERNAL CLOCK SIGNAL - A clock generator includes a first input end and a second input end. The first input end is capable of receiving a first clock signal including a first state transition and a second state transition defining a first pulse width. The second input end is capable of receiving a second clock signal having a third state transition. A time period ranges from the first state transition to the third state transition. The clock generator can compare the first pulse width and the time period. The clock generator can output a third clock signal having a second pulse width ranging from a fourth state transition to a fifth state transition. The fifth state transition of the third clock signal is capable of being triggered by the second state transition of the first clock signal or the third state transition of the second clock signal depending on the comparison of the first pulse width and the time period. | 09-30-2010 |
| 20110090753 | POWER MANAGEMENT - An SRAM includes circuitry configured for the SRAM to operate at different operation modes using different voltage levels wherein the voltage level and thus the supply current leakage is regulated based on the operation mode. For example, the SRAM, in a normal operation mode, consumes power as other SRAMs. In a deep sleep mode the supply voltage (e.g., VDDI) for the bit cell in the SRAM macro is lowered by about 20-40% of the SRAM supply voltage (e.g., VDD), sufficient to retain the data in the bit cell. When access to the SRAM is not needed, the SRAM operates in the sleep mode, consuming little or no power. | 04-21-2011 |
| 20110188326 | DUAL RAIL STATIC RANDOM ACCESS MEMORY - A static random access memory (SRAM) macro includes a first power supply voltage and a second power supply voltage that is different from the first power supply voltage. A precharge control is connected to the second power supply voltage. The precharge control is coupled to a bit line through a bit line precharge. At least one level shifter receives a level shifter input. The level shifter converts the level shifter input having a voltage level closer to the first power supply voltage than the second power supply voltage to a level shifter output having a voltage level closer to the second power supply voltage than the first power supply voltage. The level shifter output is provided to the precharge control. | 08-04-2011 |
| 20110194362 | WORD-LINE DRIVER USING LEVEL SHIFTER AT LOCAL CONTROL CIRCUIT - A representative circuit device includes a local control circuit having a level shifter, wherein in response to receipt of a first address signal the level shifter shifts the first address signal from a first voltage level to a second voltage level, providing a level shifted first address signal; and a word-line driver having at least one input for receiving a plurality of address signals, wherein the at least one input includes a first input that is coupled to the local control circuit to receive the level shifted first address signal, and an output that is electrically coupled to a word line of a memory cell array. | 08-11-2011 |
