摘要： First circuitry is powered by a first power supply domain and provides a data signal referenced to the first power supply domain. Second circuitry is powered by a second power supply domain that differs from the first power supply domain. The data signal becomes referenced to the second power supply domain by a clocked level shifter that couples the first circuitry to the second circuitry and buffers the data signal from the first power supply domain to the second power supply domain by only using a single supply voltage. The clocked level shifter is clocked by a signal that is used to precharge a first node and a second node of the clocked level shifter until the data signal is valid for at least a setup time period. The first and second nodes are precharged to establish a known state in the clocked level shifter.

摘要： In accordance with at least one embodiment, column level power control granularity is provided to control a low power state of a memory using a drowsy column control bit to control the low power state at an individual column level to protect the memory from weak bit failure. In accordance with at least one embodiment, a method of using a dedicated row of bit cells in a memory array is provided wherein each bit in the row controls the low power state of a respective column in the array. A special control signal is used to access the word line, and the word line is outside of the regular word line address space. A mechanism is provided to designate the weak bit column and set the control bit corresponding to that particular column to disable the drowsy/low power state for that column.

摘要： A sensor circuit performs a method for sensing on-chip characteristics. The method includes generating a first voltage using a drive current through a first set of transistors that are operating in saturation mode and generating a second voltage using subthreshold leakage current from a second set of transistors that are in subthreshold mode. The method further includes comparing the second voltage to the first voltage to sense an on-chip characteristic. The sensed on-chip characteristic can be temperature and/or gate length variation.

摘要： A technique for addressing single-event latch-up (SEL) in a semiconductor device includes determining a location of a parasitic silicon-controlled rectifier (SCR) in an integrated circuit design of the semiconductor device. In this case, the parasitic SCR includes a parasitic pnp bipolar junction transistor (BJT) and a parasitic npn BJT. The technique also includes incorporating a first transistor between a first power supply node and an emitter of the parasitic pnp BJT in the integrated circuit design. The first transistor includes a first terminal coupled to the first power supply node, a second terminal coupled to the emitter of the parasitic pnp BJT, and a control terminal. The first transistor is not positioned between a base of the pnp BJT and the first power supply node. The first transistor limits current conducted by the parasitic pnp bipolar junction transistor following an SEL.
