  • Patent number: 10833664
    Abstract: An apparatus for delaying a signal transition is disclosed. The apparatus includes a first circuit coupled to a first power supply signal and a second, different power supply signal. The first circuit may be configured to, based on a voltage level of a logic signal, sink a current from an intermediate circuit node. A value of the current may be based upon a voltage level of the second different power supply signal. The apparatus also includes a second circuit coupled to the first power supply signal. The second circuit may be configured to generate an output signal based upon a voltage level of the intermediate circuit node. An amount of time between a transition of the logic signal and a corresponding transition of the output signal may be based on an amount of the current.

  • Patent number: 10217494
    Abstract: A memory that includes multiple banks, each of which include multiple data storage cells, is disclosed. A decoder circuit may be configured to receive and decode information indicative of an address, and select a particular bank based on the decoded information. A first latch circuit coupled to a particular global bit line, which is, in turn, coupled to the particular bank, may generate multiple local clock signals using the decoded information and store data based on a voltage level of the particular global bit line using the plurality of local clock signals. Other circuits may also pre-charge the particular global bit line using a particular local clock signal of the plurality of local clock signals.
