    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.

    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: An apparatus and method for combating the effects of bias temperature instability (BTI) in a memory cell. Bit lines connecting to a memory cell contain two alternate paths criss-crossing to connect a lower portion of a first bit line to an upper portion of a second bit line, and to connect a lower portion of the second bit line to an upper portion of the first bit line. Alternative to activating transistors on the bit lines to read and write to the memory cell, transistors on the alternative paths may be activated to read and write to the memory cell from the opposite bit lines. The memory cell may be read through the bit lines to a sense amplifier, the transistors on the bit lines are subsequently deactivated and the transistors on the alternate paths are activated to write transposed bit values to the memory cell, thereby reversing the biases.

    摘要: A method for evaluating memory cell performance provides for circuit delay and performance measurements in an actual memory circuit environment. A row in a memory array is enabled along with a set of drive devices that couple each bitline pair to the next in complement fashion to form a cascade of memory cells. The drive devices can be inverters and the inverters can be sized to simulate the bitline read pre-charge device and the write state-forcing device so that the cascade operates under the same loading/drive conditions as the operational with memory cell read/write circuits. The last and first bitline in the row can be cascaded, providing a ring oscillator or the delay of the cascade can be measured in response to a transition introduced at the head of the cascade. Weak read and/or weak write conditions can be measured by selective loading.
