The first transistor is coupled between a first power supply node and an emitter of the parasitic pnp BJT. 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 BJT following a single-event latch-up (SEL) event.

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.
