The digital control code is generated based on the quantized code. Full Article
ng Power savings mode for memory systems By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A system and method are disclosed to accomplish power savings in an electronic device, such as a memory chip, by performing selective frequency locking and subsequent instantaneous frequency switching in the DLL (delay locked loop) used for clock synchronization in the electronic device. By locking the DLL at a slow clock frequency, the operational frequency may be substantially instantaneously switched to an integer-multiplied frequency of the initial locking frequency without losing the DLL lock point. This DLL locking methodology allows for faster frequency changes from higher (during normal operation) to lower (during a power saving mode) clock frequencies without resorting to gradual frequency slewing to conserve power and maintain DLL locking. Hence, a large power reduction may be accomplished substantially instantaneously without adding complexity to the system clock generator. Because of the rules governing abstracts, this abstract should not be used in construing the claims. Full Article
ng Low-power dual-edge-triggered storage cell with scan test support and clock gating circuit therefore By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A storage cell having a pulse generator and a storage element is proposed. The storage element input is connected to receive a data input signal. The storage element output is connected to provide a data output signal. The storage element is operable in one of a data retention state and a data transfer state in response to a storage control signal received from the pulse generator. The pulse generator is connected to receive a clock signal with rising and falling clock signal edges and is adapted to provide control pulses in the storage control signal. Each control pulse has a leading edge and a trailing edge. The control pulses have a polarity suited to invoke the data transfer state on their leading edges. The novel feature is that the pulse generator is adapted to initiate a rising-edge control pulse when receiving a rising clock signal edge and to initiate a falling-edge control pulse when receiving a falling clock signal edge. In this way, a dual-edge-triggered flip-flop may be made using only combinatorial logic circuitry and one level- or single-edge-triggered storage element. The storage cell has low power consumption, facilitates scan testing and can be used by existing design tools and test equipment. Full Article
ng Resonant clock distribution network architecture for tracking parameter variations in conventional clock distribution networks By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A resonant clock distribution network architecture is proposed that enables a resonant clock network to track the impact of parameter variations on the insertion delay of a conventional clock distribution network, thus limiting clock skew between the two networks and yielding increased performance. Such a network is generally applicable to semiconductor devices with various clock frequencies, and high-performance and low-power clocking requirements such as microprocessors, ASICs, and SOCs.
