摘要： At least one N-type transistor and at least one P-type transistor separate from the digital circuit are sized to represent the total area of the corresponding type transistors in the digital circuit. The gates of the N-type transistor and P-type transistors are set to voltages according to the corresponding off-state logic levels of the digital circuit. The N-type and P-type transistors form a portion of corresponding current mirror circuits, which can provide outputs to a leakage current monitor and/or a control circuit such as a comparator that determines when leakage current for the N-type or P-type devices has exceeded a threshold. The output of the measurement/control circuit can be used to determine a temperature of and/or control operation of the digital circuit or the system environment of the integrated circuit.

摘要： A leakage current monitor circuit provides an accurate statistically representative analog of true off-state leakage current in a digital circuit integrated on a die. At least one N-type transistor and at least one P-type transistor separate from the digital circuit are sized to represent the total area of the corresponding type transistors in the digital circuit. The gates of the N-type transistor and P-type transistors are set to voltages according to the corresponding off-state logic levels of the digital circuit. The N-type and P-type transistors form a portion of corresponding current mirror circuits, which can provide outputs to a leakage current monitor and/or a control circuit such as a comparator that determines when leakage current for the N-type or P-type devices has exceeded a threshold. The output of the measurement/control circuit can be used to determine a temperature of and/or control operation of the digital circuit or the system environment of the integrated circuit.

摘要： A method and system for determining element voltage selection control values for a storage device provides energy conservation in storage arrays while maintaining a particular performance level. The storage device is partitioned into multiple elements, which may be sub-arrays, rows, columns or individual storage cells. Each element has a corresponding virtual power supply rail that is provided with a selectable power supply voltage. At test time, digital control values are determined for selection circuits for each element that set the virtual power supply rail to the minimum power supply voltage, unless a higher power supply voltage is required for the element to meet performance requirements. The set of digital control values can then be programmed into a fuse or used to adjust a mask at manufacture, or supplied on media along with the storage device and loaded into the device at system initialization.
