20090016141 | Methods and Arrangements for Enhancing Power Management Systems in Integrated Circuits - Methods and arrangements to configure power management systems for integrated circuits are provided herein. A group of IC components that are functionally distinct or have mutually exclusive and/or quasi-mutually exclusive, (ME/QME) operating patterns (i.e. alternate or partially overlapping duty cycles) can be powered with a single power cell. An integrated circuit design tool can identified components in an integrated circuit design that have the ME/QME operating patterns.

20090016142 | SEMICONDUCTOR MEMORY DEVICE, AND METHOD OF CONTROLLING THE SAME - An internal voltage generator when activated, generates an internal voltage to be supplied to an internal circuit. Operating the internal voltage generator consumes a predetermined amount of the power. In response to a control signal from the exterior, an entry circuit inactivates the internal voltage generator. When the internal voltage generator is inactivated, the internal voltage is not generated, thereby reducing the power consumption. By the control signal from the exterior, therefore, a chip can easily enter a low power consumption mode. The internal voltage generator is exemplified by a booster for generating the boost voltage of a word line connected with memory cells, a substrate voltage generator for generating a substrate voltage, or a precharging voltage generator for generating the precharging voltage of bit lines to be connected with the memory cells. | 2009-01-15 |

A coupling circuit controllably permits charge sharing between a selectable one of the bit lines and the first input. A timing circuit is arranged to signal operation in a first phase, when the word lines have selected a row of the matrix, followed by a second phase. The timing circuit controls the coupling circuit to permit charge sharing between the input and the selectable one of the bit lines in the first phase. In the second phase the timing circuit controls the coupling circuit to prevent charge sharing, makes the reference circuit deactivate driving the reference voltage, and subsequently activates amplification by the differential sense amplifier. Preferably the timing circuit contains a dummy bit line and a trigger circuit for triggering the second phase when a potential swing on the dummy bit line exceeds a threshold value. | 2009-01-15 |
