    摘要: 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.

    摘要: 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.
