Improved transistor array device performance is obtained by use of bias voltage regulation which tracks with a fraction of a monitor transistor threshold voltage. The circuitry and methods are especially useful for improving the performance of transistor array devices such as DRAM and embedded DRAM. These benefits are obtained especially when at least two bias voltages normally supplied to the array are regulated by tracking with a fraction of an actual threshold voltage of at least one monitor transistor. Performance improvements include improved reliability, wider operational bias conditions, reduced power consumption and (in the case of memory cells) improved retention time.
