Performance increase technique for use in a register file having dynamically boosted wordlines

摘要

This invention overcome the problems inherent in the prior art for increasing the performance of a register file that is constructed to include dual-V_t bitlines or single-V_t bitlines. The invention provides a boost of the drive signal for one of the transistors of a bitline circuit, preferably for the high voltage threshold read-selection transistor of a local bitline (LBL) circuit. The drive signal amplitude is made greater than the normal supply voltage by some increment delta V.
